NU2212 is NU-type single row cylindrical roller bearing. NU structural design features double ribs on outer ring and rib-free inner ring, allowing limited axial sliding between inner and outer rings. This bearing mainly withstands heavy radial loads. The roller and inner ring assembly can be separated from outer ring, simplifying assembly, disassembly and routine maintenance. Widely used in industrial gearboxes, centrifugal pumps, compressors, conveyors and medium-heavy load rotating mechanical assemblies.
Formal quotation will be sent within 24 hours upon your inquiry.
