GQZ NU205 Single Row Cylindrical Roller Bearing 25×52×15mm Separable Bearing For Medium-Duty Gear Units

NU205 is NU-type single row cylindrical roller bearing. NU structure features double ribs on outer ring and rib-free inner ring, which allows axial displacement between inner ring and outer ring within a certain range. The bearing can withstand heavy radial loads. Roller assemblies are separable from the outer ring, facilitating separate installation, disassembly and maintenance. Widely applied in gearboxes, small reducers, pumps, compressors and medium-load rotating mechanical assemblies.
