Bearing with a riveted stamped metal cage
Filled with a polyalkylene glycol/ graphite mix for lubrication
Running-in period necessary to distribute the lubricant within the bearing for applications that stand idle for an extended period
Not for wet or humid environments
Single-row, pre-lubricated, ordinary accuracy.
Deep Deep Groove Ball Bearing china groove Ball Bearings are just about the most trusted rolling bearings. They are used to support radial and axial loads in both guidelines.
With small friction and high-limit speed, Ball Bearings are cost-effective and require little maintenance.
Chromium Metal (GCr15) made with heat treating, provides great and uniform hardness, very good wear resistance, and large contact fatigue performance.
Suitable for all types of industrial equipment, micro motor, tiny rotary motor, office equipment and so on.
Cages - Selection of cage types to suit your application needs: steel, sound brass or polymer
High Quality Steel - Ultra clean steel designed to extend bearing life simply by up to 80%
Advanced Grease Technology - NSK lubricants made to extend grease lifestyle and improve bearing performance
Extremely Finished Raceways - Specially honed to reduce noise and increase the grease distribution
Patented Seals - Give a barrier to contamination in hard environments.
Electrically insulated ball bearings available
Outer diameters up to 2500 mm
This kind of ball bearing it often the most popular due to its versatility. They will be suitable for high speeds and may handle a good radial load capability, all will very little maintenance required.
“Deep Groove” refers to the race (the groove where in fact the balls relax). There is therefore a larger space between your inner and outer bands, compared to 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) and to ensure their free rotation while transmitting the strain between them. At huge rotational speeds (for instance in gyro ball bearings), this application could be extended to include free rotation without almost have on in the bearings. To achieve this, the two parts of the bearing could be separated by a coating of adhesive fluid film called an elastic hydrodynamic lubricating film. remarked that flexibility could be maintained not only when the bearing bears the strain on the shaft, but as well when the bearing is definitely preloaded in order that the positioning precision and steadiness of the shaft does not surpass 1 microin or 1 nanoin. Hydrodynamic lubricating film.
Deep groove ball bearings mainly take radial load, but also can support radial and axial load. When the only radial loads, the get in touch with angle is zero.
When the deep groove ball bearings with a larger radial clearance, with angular speak to bearings can bear huge axial load, deep groove ball bearing friction coefficient is little, the speed limit can be high.
Sole row deep groove ball bearings will be manufactured as open up type (unsealed), sealed and shielded, the most used sizes of deep groove ball bearings happen to be also produced in sealed versions with shields or speak to seals using one or both sides, the bearings with shields or seals on both sides will be lubricated forever and are maintenance free. A sealed bearings seals has got get in touch with on the bearings inner and external, a shielded bearings shield features contact on the outer simply, and Shielded bearings are primarily designed for applications where in fact the inner ring rotates. If the external ring rotates, there is a risk that the grease will leak from the bearing at huge speeds.
Double-row Deep Groove Ball Bearing possess deep uninterrupted raceways and large conformity between your balls and raceways.
They are able to carry axial loads performing in both directions in addition to radial loads.Dual row deep groove ball bearings will be
very well suited for bearing arrangements where the load carrying ability of a single row bearing is inadequate. For the same
outside the house and bore diameters, twice row bearings are a little wider than one row bearings but have 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 style to standard sole row deep groove ball bearings of the same size. They haven't any filling slots and may accommodate normal axial loads in addition to radial loads. The radial inner clearance is usually a multiple of C5 to prevent the bearings from seizing, even though they cool speedily. All surfaces of the bearing and shields happen to be manganese phosphated to improve adhesion of the lubricant to the steel and provide additional safety against corrosion.
