Inline Planetary Equipment Reducer Options
Gearboxes are known by many different titles, including equipment drives, reducers, gear reducers, speed reducers, and gearmotors. All terms can be used pretty much interchangeably when refering to inline planetary equipment reducers.
Spur In-Line Gearboxes
Ever-Power offers a full line of compact, light-weight spur gear inline planetary equipment reducers. These inline gearboxes can be direct installed to motors or used in combination with shaft coupling. Ratios from 2:1 to 625:1 can be found, with torque values ranging from 0.13Nm to 90Nm.
Input velocity: up to 4,000 RPM
Precision machined aluminum housing
Dual ball bearings on all shafts
Encoder Low Backlash In-Line Gearboxes
These compact, lightweight, low backlash gear drives are designed specifically for encoder applications. They employ a low moment of inertia at the shaft insight, and are rated for insight speeds up to 3,000 RPM. Gear ratios from 4.96:1 to 3600:1 are available, in two frame sizes. Synchro cleats for our encoder gearboxes are available from stock.
Output torque: 1 oz.-inch
Backlash: 15 arc-minutes (in any ratio)
Ratios from 4.96:1 to 3600:1
Input speeds up to 3,000 RPM
Diameter: 1-1/16” or 1-3/4”
Black anodized aluminum housing
303 stainless gears and shafts
Ball bearings
Low Backlash Inline Taper Gearboxes
Our taper gearmotors are inline planetary gear reducer boxes with backlash equal to or better than 8 arc/minute. These inline gearboxes are created for applications where space is limited, and are available either as a shaft input or installed to a 24V DC motor.
Low backlash: ≤8 arc/min. at input
Compact design
Shaft input or with mounted motor
Ratios from 2:1 to 16:1
Output torque values from 1.14Nm to 12.7Nm
Epicyclic (Planetary) Servo Gearboxes
The Ever-Power line of internal epicyclic servo reducers are really rugged and compact. These planetary gearboxes have fully-machined housings (light weight aluminum or steel), and are outfitted with ball bearings throughout. Our inline planetary gear reducers offer flexible electric motor mounting options and can deliver result torques up to 380 Nm. Ratios from 3:1 to 36:1 are available.
Low backlash: ≤30 arc/min. at input
Input speeds because high as 3,000 RPM
Precision machined aluminum housings
Dual ball bearings on all shafts
Available in ratios from 3:1 to 36:1
Output torques as high as 380Nm
Speed Increaser Gearboxes
Our low ratio Encoder gearboxes and inline taper gearboxes may also be used as gear quickness increasers, if needed.
The Ever-Power Advantage: 30 years of Unparalleled Quality
Greased for life
Input speeds as high as 4,000 RPM
Available with equipment ratios up to 3600:1
Customized gearboxes available

GEARBOX REDUCERS
Correct angle gearboxes (worm and planetary) are rugged and built for 90° turns. Inline reducers (parallel shaft and planetary) are a perfect match for motors with high insight speeds, or when gearmotor effectiveness is important.
