1. Product Overview 7212B is single row angular contact ball bearing. Suffix B represents 40° contact angle. It can bear combined radial load and unidirectional axial load. Larger contact angle provides stronger axial bearing capacity compared to A and C variants. For bidirectional axial load requirements, bearings need to be installed in paired configurations. Widely applied in industrial gearboxes, air compressors, centrifugal pumps, fan assemblies and medium-heavy load
