NJ211E.M1 Single Row Cylindrical Roller Bearing 55x100x21mm Brass Cage For Gearbox 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 lubrication 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.
