Bearings are ball

These bearings ball are intended for perception of radial and axial loadings. Bearings ball are capable to perceive axial loading only in one direction therefore for fixing of a shaft in both parties they are installed, as a rule, on two on a shaft or in a support. Racetracks in both rings of this bearing are executed so that the angle of contact which has different values depending on a design is formed. With increase in an angle of contact the axial loading capacity of the bearing increases.
