GQZ NU210 Single Row Cylindrical Roller Bearing 50×90×20mm For Gear Units And Medium-Heavy Load Machinery

NU210 is NU type single row cylindrical roller bearing. NU structure adopts double ribs on outer ring and rib-free inner ring, allowing certain axial displacement between inner ring and outer ring. This bearing can withstand heavy radial loads. The roller and inner ring assembly can be separated from outer ring, which brings convenience for installation, disassembly and routine inspection. Widely used in industrial gearboxes, water pumps, compressors, conveyors and medium-heavy load transmission rotating assemblies.
