7312B is single row angular contact ball bearing. The suffix B stands for 40° contact angle. It can bear combined radial load and unidirectional axial load. Larger contact angle delivers superior axial bearing capability compared with A and C type versions. Bearings need to be installed in paired arrangement when bidirectional axial load exists. Widely used in industrial gearboxes, heavy-duty water pumps, air compressors, mining machinery and medium-heavy load rotary assemblies.
