The introduction of angular contact ball bearings

Angular contact ball bearings mainly bear large one-way axial load, the greater the contact Angle, the greater the load bearing capacity. The cage is made of steel plate, brass or engineering plastics, and is formed by stamping or turning, depending on the form of bearing or the conditions of use. Other bearings include combination angular contact ball bearings, double row angular contact ball bearings and four-point contact ball bearings.
Angular contact ball bearings can bear both radial and axial loads. Able to work at high speed. The larger the contact Angle, the higher the axial bearing capacity. High precision and high speed bearings usually take 15 degrees of contact Angle. Under the action of axial force, the contact Angle will increase. Single row angular contact ball bearings can only bear axial load in one direction. When bearing radial load, additional axial force will be caused. And only limit the axial displacement of the shaft or housing in one direction. If installed in pairs, make the outer ring of a pair of bearings opposite, that is, the wide end faces the wide end face and the narrow end faces the narrow end face. This avoids causing additional axial forces and allows the shaft or housing to be confined within the axial clearance in both directions.
Because the raceway of the inner and outer rings of angular contact ball bearing can have relative displacement on the horizontal axis, it can bear both radial load and axial load -- combined load (single row angular contact ball bearing can only bear one direction axial load, so it is usually installed in pairs). The material of the cage is brass, synthetic resin, etc., according to the bearing form, the use of the conditions and distinguish.
