Rail transit

Applied to the axle box of railway freight cars, subways, light rail, and trams, it bears the overall weight and inertial forces of the carrying carriages, providing stable, efficient, and safe transportation support for rail transit vehicles.

Mastering multiple key technologies to meet various performance requirements for rail transit bearing cages, including high load capacity, long service life, and maintenance-free operation.

Rail transit

Applications and Products

Copper cage for traction motor bearings

Copper cage for traction motor bearings

The copper cage of the traction motor bearing is made of copper material, which has good thermal conductivity and corrosion resistance. It helps to quickly dissipate the heat generated during the operation of the bearing, thereby reducing the operating temperature of the bearing and extending the service life of the cage.
Gearbox bearing copper cage

Gearbox bearing copper cage

The bearing cage of the gearbox is a bearing component used in the gearboxes of railway vehicles, which needs to withstand high speed, high load, high temperature, high vibration, and impact loads. The cage needs to have sufficient strength and rigidity to maintain the uniform distribution of rolling elements and the stable operation of the bearing.
Axle box bearing cage

Axle box bearing cage

The axle box bearing cage is an important component in the axle box of railway vehicles, used to support the wheelset and transmit the weight and load of the vehicle. The design of the axle box bearing cage needs to meet the requirements of high speed, high load, high temperature, and harsh environmental conditions.
Plastic steel isolation ring

Plastic steel isolation ring

The plastic steel spacer component is a part used between the bearing rear stop and the inner ring in rail transit. Its main function is to ensure that no micro-vibration wear particles are generated between the contact surfaces, thereby reducing the friction between the inner ring and the rear stop, avoiding micro-vibration wear, and extending the service life of the bearing. It also helps to provide a longer grease life and maintenance cycle.
Railway dust cover

Railway dust cover

The railway dust cover is an important sealing component of rail transit bearings. Its main function is to prevent external dust, moisture, and other impurities from entering the bearing while reducing the leakage of lubricating grease. It also provides good strength and corrosion resistance, making it suitable for harsh working environments. It has a simple structure, is easy to install, and has low maintenance costs.
