Angular Contact Ball Bearings

Angular Contact Ball Bearings Angular Contact Ball Bearings


LYC’s angular ball bearings are also called angular contact radial thrust ball bearings. This type of bearing is particularly suitable for carrying combined loads (radial and axial load) as well as pure axial loads and can be operated at relatively high speeds. The axial load carrying capacity of angular contact ball bearings changes along with dimensions of contact angle. The larger the contact angle, the better the axial load carrying capacity is. The contact angle α is defined as the angle between the line joining the contact points 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.


Minimum Load-Angular Contact Ball Bearings

In order to keep bearings working in a good condition, a minimum load must be imposed on bearings, particularly on bearings working at high speeds, high accelerations, or with the load direction changing frequently, because under these working conditions, inertial force of balls and cage and lubricant friction will have bad influence on the rotation of bearings, and detrimental sliding movement may be caused.
