2. About Our Aluminum Straight Bore Timing Pulley With Belt Width 10MM<\/h2>\n

The EP-T5 is a DIN 7721-compliant ko\u0142o rozrz\u0105du z prostym otworem<\/strong> manufactured in aluminum, designed for use with T5-profile timing belts at a 10 mm belt width. The T5 pitch of 5 mm places this series firmly in the compact, high-speed drive category \u2014 smaller pitch means more teeth in contact at any given arc of wrap, producing smoother torque transfer and reduced per-tooth load at the operating speeds typical of servo-driven automation axes and stepper motor positioning systems. With 21 standard models spanning 10 to 60 teeth, the EP-T5 10 mm series covers an exceptionally wide range of speed ratios and drive geometries from a single standardized component family.<\/p>\n

Each model in this aluminum straight bore timing pulley<\/strong> range is machined to the type code 6F for the 10 to 42-tooth variants \u2014 meaning a flanged configuration that keeps the T5 belt seated laterally on the pulley face \u2014 and type code 6 for the larger 44, 48, and 60-tooth models where the wider hub diameter (Dm up to 65 mm) provides adequate belt guidance through the housing design. The straight bore (d) starts at 8 mm for models from 27 teeth upward, while the smallest 10 to 26-tooth variants ship with an unfinished bore indicated by \u201c\u2013\u201d in the catalog, allowing the user to machine the bore to their required shaft diameter. The consistent hub length L of 21 mm across all models simplifies drive shaft layout across different tooth-count selections within the same machine design.<\/p>\n

3. Pi\u0119\u0107 kluczowych zalet produktu<\/h2>\n
\n
\n
\u25b6 DIN 7721 Standard Compliance<\/div>\n

Conformance to the German DIN 7721 standard for metric pitch timing pulleys ensures that this T5 series ko\u0142o rozrz\u0105du z prostym otworem<\/strong> is dimensionally interchangeable with T5 belts and mating pulleys from any manufacturer who also references DIN 7721. For European OEM machine builders and global automation engineers who source replacement belts and pulleys from multiple suppliers across different purchasing cycles, this standards compliance is the key guarantee of interoperability and a major procurement advantage over non-standard or proprietary drive components.<\/p>\n<\/div>\n

\n
\u25b6 Lightweight Aluminum Construction<\/div>\n

Aluminum construction reduces the rotating inertia of the drive system compared to steel or cast iron pulleys of equivalent size. In servo and stepper motor-driven positioning axes \u2014 which make up the majority of T5 timing pulley applications \u2014 lower inertia translates directly to faster acceleration and deceleration, shorter cycle times, and lower motor heating during high-duty-cycle operation. The aluminum alloy used in this aluminium timing pulley<\/strong> series also provides a natural oxide layer that resists corrosion in normal indoor automation environments without requiring additional surface treatment.<\/p>\n<\/div>\n

\n
\u25b6 Consistent 21 mm Hub Length Across All Models<\/div>\n

Every model in the EP-T5 10 mm series shares an identical hub length L of 21 mm and belt width F of 15 mm. This dimensional consistency is a deliberate design feature that simplifies machine layout: once a designer selects the T5 10 mm belt width for a drive axis, the axial space claimed by the pulley on the shaft is fixed regardless of the tooth count selected. Changing the speed ratio of the drive by substituting one tooth count for another requires no modification to the shaft length, bearing spacing, or housing width \u2014 a significant benefit for modular machine designs where drive ratio optimization continues after initial layout is frozen.<\/p>\n<\/div>\n

\n
\u25b6 Wide Tooth Count Range for Ratio Flexibility<\/div>\n

Twenty-one standard models from 10 to 60 teeth give engineers the ability to achieve speed ratios from 1:1 up to 6:1 using only standard catalog parts within this series. Intermediate ratios can be achieved through careful pairing of drive and driven pulleys from the range. For example, a 15-tooth drive pulley combined with a 30-tooth driven pulley gives a precise 2:1 speed reduction \u2014 both available as standard timing pulley stock items. This range breadth reduces the need for custom timing pulleys in most standard automation and positioning applications.<\/p>\n<\/div>\n

\n
\u25b6 Flanged Design for Reliable Belt Tracking<\/div>\n

The 6F type designation on models from 10 to 42 teeth indicates that these pulleys are supplied with a retaining flange on both sides of the toothed belt-running surface. Flanges prevent the T5 timing belt from walking off the pulley edge during operation, which can otherwise occur when the belt runs under lateral load in open-frame machines, or when small misalignments between shafts cause a gradual belt tracking drift. Reliable belt tracking without external guide rails reduces machine assembly complexity and eliminates the need for a separate timing belt tensioner pulley with lateral guide function in most drive configurations.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

4. Working Principle<\/h2>\n

The EP-T5 ko\u0142o rozrz\u0105du z prostym otworem<\/strong> operates on the principle of positive-engagement synchronous drive. The trapezoidal tooth profile machined into the pulley’s outer circumference \u2014 conforming to the DIN 7721 T5 tooth form \u2014 meshes precisely with the corresponding tooth cavities on the inner surface of a T5 timing belt. When the motor shaft rotates the drive pulley, each tooth of the ko\u0142o pasowe paska rozrz\u0105du<\/strong> pushes against the mating belt tooth in the engaged arc. Unlike V-belt or flat-belt drives where power transfer depends on friction, every rotation of the drive pulley moves the belt by exactly (N \u00d7 pitch) millimetres, where N is the number of engaged tooth pitches. This produces zero-slip synchronous motion at the driven pulley or linear motion at the belt’s loaded strand.<\/p>\n

The pitch diameter formula for this ko\u0142o rozrz\u0105du z prostym otworem<\/strong> follows the relationship Dp = (N \u00d7 5) \/ \u03c0, which gives pitch diameters from 15.92 mm for the 10-tooth model to 95.52 mm for the 60-tooth model in this series. The outside diameter De is always 0.76 to 0.87 mm smaller than Dp \u2014 a consistent offset that reflects the T5 tooth depth \u2014 ensuring that the belt pitch line aligns with the theoretical pitch circle at which the speed ratio calculation is based. The flange diameter Df on 6F type models is sized to exceed De by 4 to 8 mm, creating a raised rim that physically prevents the belt from sliding off the pulley face during operation, particularly important in high-speed automation drives where lateral belt forces are intermittent and difficult to predict analytically.<\/p>\n

Belt tension in a T5 timing belt drive system is set during installation to achieve adequate contact force between belt tooth root and pulley tooth flank across the full arc of contact on the drive pulley. Unlike friction drives, a timing belt drive does not require high pretension to transmit torque \u2014 only enough tension to prevent belt tooth jump under peak torque conditions. For most EP-T5 10 mm belt width applications, the T5 belt manufacturer’s recommended installation tension is in the range of 20 to 40 N, which is easily achieved by deflecting the belt at mid-span between pulleys during assembly. This low installation tension means shaft and bearing loads from the timing belt drive are comparatively small, extending bearing life in the machine.<\/p>\n<\/div>\n

\n

5. Material: Aluminum Alloy<\/h2>\n

The EP-T5 series aluminum ko\u0142o rozrz\u0105du z prostym otworem<\/strong> is manufactured from a high-strength aluminum alloy \u2014 typically equivalent to EN AW-6061 T6 or EN AW-6082 T6 \u2014 which offers a well-balanced combination of machinability, corrosion resistance, tensile strength, and weight efficiency for precision timing pulley applications. The alloy’s tensile strength in the T6 heat treatment condition typically exceeds 290 MPa, which is more than adequate for the tooth root bending stresses encountered in standard T5 10 mm belt width drives at the speeds and torques for which this series is rated.<\/p>\n

The natural oxide layer that forms on aluminum surfaces in ambient air provides effective corrosion protection in typical indoor automation environments \u2014 electronics assembly, laboratory equipment, packaging machinery \u2014 without requiring paint or plating. For applications in more aggressive environments \u2014 occasional moisture exposure, mild chemical splash, or requirements for a specific color coding for visual identification \u2014 the aluminum alloy substrate of this aluminium timing pulley<\/strong> is readily anodizable to produce hard, wear-resistant anodic oxide coatings in natural silver, black, or other colors. Anodizing also slightly reduces the effective bore and outside diameter dimensions, so users intending to anodize after machining should allow appropriate machining stock on the bore and flange diameters.<\/p>\n

The choice of aluminum over steel for this T5 series reflects the application context: T5 timing belt drives are most commonly used in compact, high-speed positioning axes driven by stepper or servo motors where reducing rotating inertia directly improves dynamic response. An aluminum T5 pulley weighs approximately one-third of a steel pulley with identical dimensions, which significantly reduces the reflected inertia at the motor shaft. This inertia reduction is especially important in multi-axis machine designs where the combined inertia of all drive pulleys can otherwise mismatch the motor rotor inertia and compromise servo tuning stability across the machine’s operating speed and load range.<\/p>\n<\/div>\n

The EP-T5 aluminum ko\u0142o rozrz\u0105du z prostym otworem<\/strong> with 10 mm belt width addresses the compact end of the synchronized drive market, where space is constrained, motor inertia matching is critical, and position accuracy must be maintained across many millions of duty cycles. The following represent the primary deployment contexts for this series.<\/p>\n

\n
\n

3D Printing and Additive Manufacturing<\/h3>\n

Desktop and industrial 3D printers \u2014 FDM, SLA, and SLS variants \u2014 use T5 timing belt drives for their X, Y, and sometimes Z positioning axes. The EP-T5 10 mm series ko\u0142o rozrz\u0105du z prostym otworem<\/strong> is sized precisely for the motor shaft diameters and frame dimensions of most common 3D printer drive systems. Aluminum construction reduces the axis inertia seen by the stepper motor, enabling faster acceleration and sharper directional changes in the print head or build platform without losing step position. Manufacturers of desktop printers in Germany, Japan, and the United States frequently source metric timing belt pulleys of this specification for both OEM production and after-market repair.<\/p>\n<\/div>\n

\n

Collaborative and Industrial Robotics<\/h3>\n

Collaborative robot arms and small-scale SCARA systems use compact T5 timing belt stages to transmit servo motor torque to secondary joints and end-effector axes. The T5 5 mm pitch provides fine angular resolution per motor encoder count when driving through the gear reduction inherent in the pulley ratio, and the low mass of the aluminum T5 pulley minimizes added link inertia in each robot joint. Robotics integrators in South Korea, France, and Taiwan specify T5 series aluminum timing pulleys for end-of-arm tooling drives, camera pan-tilt units, and wafer handling gripper mechanisms where compact dimensions and precise repeatability are both required simultaneously.<\/p>\n<\/div>\n

\n

Laboratory and Medical Automation<\/h3>\n

Automated liquid handling systems, PCR thermocyclers, slide staining platforms, and diagnostic instrument sample carriages use T5 timing belt drives to move sample racks, pipette heads, and reagent dispensing mechanisms with sub-millimetre repeatability. The compact pitch and low belt tension requirement of T5 drives make them ideal for precision laboratory equipment where space is constrained and any vibration transmitted through the mechanism can affect analytical results. Regulatory environments such as FDA 21 CFR Part 820 (USA) and CE\/IVD Directive compliance (EU) require that component suppliers for medical automation equipment can provide dimensional inspection records and material traceability, which we supply on request.<\/p>\n<\/div>\n

\n

Textile and Sewing Machinery<\/h3>\n

Computerized embroidery machines, cutting plotters for fabric, and yarn feed systems in circular knitting machines use T5 belt drives to synchronize multiple thread carrier or cutting head axes at high cycle rates. The T5 series aluminum timing belt drive pulley’s combination of low inertia and precise tooth engagement makes it well-suited to the rapid direction reversals in X-Y embroidery head drives, where overshooting the commanded position due to high inertia would produce a stitch position error visible in the finished product. Textile machinery manufacturers in India, Bangladesh, and Italy represent significant end-user markets for T5 series aluminum pulleys in 10 mm belt width configurations.<\/p>\n<\/div>\n

\n

Camera, Optics, and Sensor Positioning<\/h3>\n

Motorized pan-tilt camera mounts, telescope focuser drives, spectrophotometer grating positioners, and laser scanner beam deflection stages all use T5 timing belt drives to translate motor rotation into precise angular or linear movement of the optical component. In these applications, backlash \u2014 the dead zone of motion when the drive reverses direction \u2014 must be minimized. A properly tensioned T5 timing belt drive has essentially zero backlash compared to a gear train, which makes it the preferred choice for optical positioning where bidirectional accuracy is essential. The aluminum T5 straight bore timing pulley’s low mass also avoids adding vibration to sensitive optical measurement setups.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Cz\u0119sto zadawane pytania<\/h2>\n

Questions from engineers, procurement managers, and distributors worldwide about the EP-T5 aluminum ko\u0142o rozrz\u0105du z prostym otworem<\/strong> series and T5 timing belt drive systems.<\/p>\n

\nQ1. What is a straight bore timing pulley and how is it different from a taper lock timing pulley when used in a German automation system?<\/summary>\n
A1. A straight bore timing pulley has a parallel cylindrical through-bore that slides onto the shaft and is secured by a setscrew or key, while a taper lock pulley uses a tapered bushing system to grip the shaft by wedge action. For German automation systems using DIN 7721 T5 drives, the straight bore version is typically preferred for small shaft sizes up to 8 mm where taper lock bushings are disproportionately large relative to the pulley, and where the machine builder wants the flexibility to machine the bore to a precise H7 fit at their own workshop rather than ordering a finished bore size from the supplier.<\/div>\n<\/details>\n
\nQ2. Where can I buy aluminum straight bore timing pulleys in T5 10mm belt width with fast delivery to Europe or the United States?<\/summary>\n
A2. We stock the most commonly requested tooth counts in the T5 21-series (10T5, 15T5, 20T5, 25T5, 30T5, 40T5) and can dispatch within 3 to 5 working days to European and US destinations via air freight. For less common tooth counts or custom bore requirements, production lead times are 10 to 20 working days. Contact our sales team with your specific part code, quantity, and required delivery address to receive a confirmed stock status and shipping cost quotation.<\/div>\n<\/details>\n
\nQ3. How do I calculate the correct tooth count for an aluminum T5 timing pulley to achieve a specific speed reduction ratio in my 3D printer or robotic arm?<\/summary>\n
A3. The speed ratio of a T5 timing belt drive equals the tooth count of the driven pulley divided by the tooth count of the drive pulley. For a 3:1 reduction with a 20-tooth motor pulley, select a 60-tooth driven pulley (60T5\u201321). For a 2:1 reduction with a 15-tooth drive, use a 30-tooth driven. Verify that the selected tooth counts produce pitch diameters that fit within your frame center-distance and shaft diameter constraints by using the pitch diameter formula Dp = N \u00d7 5 \/ \u03c0. Our technical team can assist with drive ratio and belt length calculations for robotic or 3D printer applications on request.<\/div>\n<\/details>\n
\nQ4. What is the difference between an HTD timing belt pulley and a T5 straight bore timing pulley and which type is better for a high-torque servo axis in Japan or South Korea?<\/summary>\n
A4. HTD pulleys use a rounded, curvilinear tooth profile designed to reduce tooth root stress concentration at high torque loads, making them better suited to heavy-duty servo axes and main drive applications. T5 pulleys use a trapezoidal tooth profile optimized for light to medium duty precision positioning at high speeds. For a servo axis in Japan or South Korea that carries high torque \u2014 such as a main robot joint or CNC axis with significant cutting force \u2014 HTD series (3M, 5M, or 8M pitch) is generally preferred. For a secondary positioning axis with moderate torque and demanding speed and accuracy requirements, the T5 series aluminum straight bore timing pulley is the more appropriate choice.<\/div>\n<\/details>\n
\nQ5. How do I get a quote for custom aluminum timing belt pulleys with a finished bore and keyway for a medical device assembly project in the United States or Canada?<\/summary>\n
A5. For custom timing belt pulleys with finished bore and keyway to DIN 6885 or ANSI B17.1 standard, please submit an inquiry specifying the part code (e.g. 20T5\u201321), required bore diameter in mm or inches, keyway width and depth, tolerance class, quantity, and delivery destination in the USA or Canada. We provide material test certificates and dimensional inspection records to support FDA 21 CFR Part 820 quality system requirements. Quotations are typically returned within 24 hours of receiving complete specifications.<\/div>\n<\/details>\n
\nQ6. What timing belt should I use with the 20T5\u201321 T5 series pulley and what does the \u201c21\u201d in the part code indicate?<\/summary>\n
A6. The \u201c21\u201d in the part code 20T5\u201321 is the belt width code for DIN 7721 T5 series, indicating compatibility with a 10 mm wide T5 timing belt. The mating belt is a standard T5-profile timing belt with 10 mm width, available in cut lengths and as endless loops from major timing belt manufacturers such as Gates, Continental, and Mitsuboshi. When ordering the belt, specify T5 profile, 10 mm width, and the required belt length in mm (must be a multiple of 5 mm for T5 standard closed-loop belts).<\/div>\n<\/details>\n
\nQ7. Are aluminum T5 timing pulleys in stock nearby for same-week dispatch to customers in Australia or Southeast Asia for urgent machine repair projects?<\/summary>\n
A7. Yes, we dispatch stocked T5 21-series aluminum pulleys to Australia and Southeast Asia destinations via international express courier with typical transit times of 3 to 7 working days. For urgent machine repair requirements, please email or use the inquiry form on this page with the subject \u201cUrgent Repair\u201d and we will prioritize stock checking and quotation response. DHL or FedEx priority shipping options are available for critical downtime situations across all major Australian and ASEAN cities.<\/div>\n<\/details>\n
\nQ8. What is the difference between a flanged (type 6F) and unflanged (type 6) T5 timing pulley and which type should I choose for my drive design?<\/summary>\n
A8. A flanged type 6F T5 ko\u0142o rozrz\u0105du z prostym otworem<\/strong> has raised rims on both sides of the toothed belt-running surface, which physically prevent the belt from walking off the pulley edge laterally. This makes 6F the default choice for most open-frame drives where no external belt guide is present. A type 6 pulley has no flanges, which simplifies the driven pulley in drives where one flanged pulley at the drive end is sufficient to keep the belt centered, or where the machine housing provides the lateral containment. For the EP-T5 21 series, models up to 42 teeth are supplied as 6F, and the 44, 48, and 60-tooth models are type 6 due to their larger hub diameter making flange addition less practical.<\/div>\n<\/details>\n
\nQ9. Which timing pulley standard sizes are available in the T5 series and how do I find a replacement for my existing T5 aluminum pulley from a different supplier?<\/summary>\n
A9. The EP-T5 21 series covers 21 standard tooth counts: 10, 12, 14, 15, 16, 18, 19, 20, 22, 24, 25, 26, 27, 28, 30, 32, 36, 40, 42, 44, 48, and 60 teeth. To identify a replacement for an existing T5 pulley, count the teeth on the existing pulley or measure its pitch diameter (Dp = measured diameter at the belt pitch line) and calculate N = Dp \u00d7 \u03c0 \/ 5. Then cross-reference the tooth count and hub dimensions (Dm, L, d) to the corresponding model in the T5\u201321 series table above. DIN 7721 conformance means our products are dimensionally compatible with T5 pulleys from any standard-compliant supplier.<\/div>\n<\/details>\n
\nQ10. Where do I find a reliable metric timing pulley manufacturer that can supply both standard and custom T5 aluminum pulleys for an OEM project in India or Brazil?<\/summary>\n
A10. We supply standard and custom T5 aluminum timing pulleys to OEM machine builders and automation integrators in India and Brazil, as well as across Latin America including Colombia, Mexico, and Chile.
