NU 1014 ECMR/HC5C4 Bore 70 Mm, Hybrid Ceramic Cylindrical Roller Bearings, Single Row For Railway Vehicle

The NU 1014 ECMR/HC5C4 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 NU 1014 ECMR/HC5C4 bearing is a Hybrid ceramic cylindrical roller bearings, single row for railway vehicle with an inner diameter of 70 mm , an outer diameter of 110 mm, a width of 20 mm. It typically uses PN grade precision tolerances and GCr15SiMn rings, HC5 = Silicon nitride Si3N4 rolling mlement.
