We develop and supply a wide range of high-performance, highly reliable, long-life, maintenance-free railway vehicle bearings for use in critical components such as axles, drive units and traction motors, thereby consistently supporting the railway industry’s core requirements for safe, stable and efficient operation.

From classic models to the latest generation of rail vehicles, our products have been successfully deployed in numerous high-speed trains. In terms of axle bearings, we offer both oil-bath lubricated bearings and sealed grease-lubricated bearings to meet the operational requirements of different vehicle types.

For drive units operating in complex vibration environments, we have long utilised our independently developed, highly reliable tapered roller bearings. These products enhance the anti-seizing performance of the flange surfaces whilst incorporating high-strength cages treated with soft nitriding, thereby further improving operational stability. In recent years, to meet the demands of reliable operation at higher speeds, we have also specifically developed flanged cylindrical roller bearings for double-helical gear drive units.

In the field of traction motor bearings, we have developed specialised cages with excellent grease replenishment performance, effectively extending maintenance intervals. To address the common issue of electrical erosion damage in the industry, we offer proven solutions such as ceramic-insulated bearings and resin-insulated bearings.
