Product Description
1. Product Overview
NU2214 is NU-type single row cylindrical roller bearing. NU structure has 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 inner ring and roller assembly can be separated from outer ring, which simplifies installation, disassembly and routine maintenance. Widely used in industrial gearboxes, water pumps, compressors, belt conveyors and various medium-heavy load rotating assemblies.
