Axial rigidity


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.

· Contact angle α = 40 °, suitable for large axial load to bear

· Contact angle α = 25 °, used for precision spindle bearings

· Contact angle α = 15 °, precision bearings used for the larger size


Angular contact ball bearings can be widely used in home appliances, electric tools, fitness equipment, medical devices, motorbikes, textile machines, autos and other areas.
