Bearing with a riveted stamped metal cage
Filled up with a polyalkylene glycol/ graphite mixture for lubrication
Running-in period required to distribute the lubricant within the bearing for applications that stand idle for a long period
Not for wet or perhaps humid environments
Single-row, pre-lubricated, regular accuracy.
Deep Groove Ball Bearings will be one of the most trusted rolling bearings. They are being used to support radial and axial loads in both guidelines.
With small friction and high-limit speed, Ball Bearings are cost-effective and need little maintenance.
Chromium Metal (GCr15) made out of heat treating, provides great and uniform hardness, good wear resistance, and excessive contact fatigue performance.
Suitable for all types of professional equipment, micro motor, tiny rotary electric motor, office equipment and so forth.
Cages – Variety of cage types to fit your application needs: steel, sturdy brass or polymer
High Quality Steel – Ultra clean metal designed to extend bearing life by up to 80%
Advanced Grease Technology – NSK lubricants designed to extend grease lifestyle and improve bearing performance
Very Finished Raceways – Specially honed to minimize noise and increase the grease distribution
Patented Seals – Give a barrier to contamination in challenging environments.
Electrically insulated ball bearings available
Outer diameters up to 2500 mm
This kind of ball bearing it often the most popular because of its versatility. They will be ideal for high speeds and may handle a good radial load capability, all will hardly any maintenance required.
“Deep Groove” refers to the competition (the groove where in fact the balls relax). There is therefore a larger space between your inner and outer rings, than the diameter of the ball. This leaves space for the rubber seals.
The purpose of a ball bearing is to determine the relative position of two parts (usually the shaft and the bearing housing) also to ensure their free rotation while transmitting the strain between them. At huge rotational speeds (for example in gyro ball bearings), this application can be extended to add free rotation without practically have on in the bearings. To achieve this, the two parts of the bearing can be separated by a layer of adhesive liquid film named an elastic hydrodynamic lubricating film. remarked that flexibility can be maintained not only when the bearing bears the load on the shaft, but also when the bearing is preloaded in order that the positioning reliability and steadiness of the shaft does not go beyond 1 microin or 1 nanoin. Hydrodynamic lubricating film.
Deep groove ball bearings mainly have radial load, but can also support radial and axial load. When the only radial loads, the contact angle is zero.
When the deep groove ball bearings with a more substantial radial clearance, with angular get in touch with bearings can bear significant axial load, deep groove ball bearing friction coefficient is little, the speed limit is also high.

Solo row deep groove ball bearings are manufactured as open type (unsealed), sealed and shielded, the most popular sizes of deep groove ball bearings happen to be also stated in sealed versions with shields or contact seals on one or both sides, the bearings with shields or seals in both sides happen to be lubricated for life and are maintenance free. A sealed bearings seals offers speak to on the bearings interior and external, a shielded bearings shield possesses speak to on the outer just, and Shielded bearings happen to be primarily designed for applications where the inner band rotates. If the external ring rotates, you will find a risk that the grease will leak from the bearing at great speeds.
Double-row Deep Groove Ball Bearing currently have deep uninterrupted raceways and excessive conformity between the balls and raceways.
They could carry axial loads acting in both directions in addition to radial loads.Twice row deep groove ball bearings will be
very suitable for bearing arrangements where in fact the load carrying ability of an individual row bearing is inadequate. For the same
outside and bore diameters, twice row bearings are a little wider than one row bearings but possess considerably higher load
carrying capacity than single row bearings in the 62 and 63 series.
EPT deep groove ball bearings for extreme temperatures correspond in design to standard one row deep groove ball bearings of the same size. They have no filling slots and may accommodate normal axial loads in addition to radial loads. The radial interior clearance is a multiple of C5 to avoid the bearings from seizing, even though they cool swiftly. All surfaces of the bearing and shields happen to be manganese phosphated to enhance adhesion of the lubricant to the metal and provide additional safety against corrosion.
