NU216ECM/C4VA3091 Bore 80 Mm, INSOCOAT Cylindrical Roller Bearings, Single Row For Railway Vehicle

The NU216ECM/C4VA3091 Axle box: Connects the wheels to the bogie, bearing vehicle loads and guiding forces. Commonly used bearings include cylindrical roller bearings, tapered roller bearings, and self-aligning roller bearings.

Traction motor: Supports the high-speed rotation of the motor rotor and requires insulation to prevent electrolytic corrosion. Commonly used bearings include deep groove ball bearings, angular contact ball bearings, and insulated cylindrical roller bearings.

Gearbox: Transmits traction power and withstands high speeds and impact loads. Commonly used bearings are a combination of cylindrical roller bearings and deep groove ball bearings.

Axle bearing (motor suspension bearing): Transmits the torque of the traction motor to the axle and accommodates axle bending. Commonly used bearings include self-aligning roller bearings or cylindrical roller bearings.

The NU216ECM/C4VA3091 bearing is a INSOCOAT cylindrical roller bearings, single row for railway vehicle with an inner diameter of 80 mm , an outer diameter of 140 mm, a width of 26 mm. It typically uses PN grade precision tolerances and GCr15SiMn rings, GCr15SiMn rolling mlement. Its dynamic radial rated load is approximately 158629 N, its static radial rated load is approximately 165121 N. It uses C4 standard radial clearance, Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
