| High Light | NJ211E.M1 cylindrical roller bearing brass cage ，55x100x21mm cylindrical roller bearing gearbox ，single row roller bearing transmission shaft | ||
NJ211E.M1 is high-load single row cylindrical roller bearing with overall dimensions 55×100×21 mm, manufactured from high-purity GCr15 bearing steel. Adopting E upgraded roller profile and solid machined brass M1 cage, it guides cylindrical rollers evenly and steadily.
Classic NJ structural layout supports heavy radial loads and single-direction axial positioning simultaneously. Separable inner and outer rings greatly simplify mounting, disassembly and maintenance. Open unsealed design adapts to oil bath / forced circulating lubriion inside closed gearbox casings, with excellent heat dissipation and lubricant circulation performance. Widely applied in gear reducers, vehicle transmissions, electric motors and various medium-high speed power transmission equipment.
