Japan NACHI bearing 7002C angular contact ball bearings
1.The definition of angualar contact ball bearing
Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis. This means that they are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.
Further, the axial load carrying capacity of angular contact ball bearings increases with increasing contact angle. The contact angle α is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the load is transmitted from one raceway to another, and a line perpendicular to the bearing axis.

3. Physical Characteristics of angular contact ball bearings
1. To face configure line towards the load bearing polymer bearing axis. Axial load carrying in both directions, although each is only by a bearing (or series bearing) load. Rigidity of this configuration is not back to back arrangement so high, is not suitable for the overturning moment.
2. To configure the bearings back to back line towards the load bearing axis divergence. Can carry axial load in both directions, although each time only by a bearing (or series bearing) load. Back to back configuration relative rigidity to withstand overturningmoment.
3. Series bearings can not be compared with group group bearing or bearing adjustment, usually in series, and back to back, or a combination of serial and face to face configuration.
4.The application of angular contact ball bearing
The products are widely used in large motor vehicles, motorcycles, spindle, internal-combustion engine, generator, gas turbines and reducer, rolling mill etc.
