In fact, Pillow Block Ball Bearing is a variant of the deep groove ball bearing, which is characterized by the effect of the surface of the outer diameter of its outer ring as the spherical surface of the ball bearing the corresponding concave spherical surface of the bearing seat. It is mainly used to bear radial and axial joint loads based on radial load. It is not suitable for axial load alone. This kind of bearing can be installed in the inner ring (with all the rollers and maintainers) and the outer ring. The size of the axial clearance of this kind of bearing has a great relationship with the normal work of the bearing. When the axial clearance is too small, Wen Sheng is higher: when the axial clearance is large, the bearing is easily damaged. Therefore, when installing and running, we should pay special attention to adjust the axial clearance of bearings, and install prestress when necessary, so as to increase the rigidity of bearings. It is often used in mining, metallurgy, agriculture, chemical industry, transportation and other machinery.
