Bearings for railway transport

Energy efficient bearing units HARP with extended resource.

FOR THE FIRST TIME SPECIALLY DESIGNED UNDER THE OPERATING CONDITIONS OF THE "SPACE 1520 ":

→ Cassette units for axle-boxes of freight and passenger cars – CRU Duplex 
→ Cassette units for axle-boxes of freight and passenger cars – TBU 1520
→ Cassette units for axle-boxes of locomotives– CRU HARP
→ Closed units for traction electric motors of locomotives – CRВ HARP

The main result of design and technology optimization is increasing of the run between repairs more than in 2.5 times (800,000 km and more).

Results of under control operation on the RZhD network: In wagons equipped with CRU Duplex bearings, increasing of operational reliability of axle components is fixed —number of axle unit repairs per year for one given wagon is in 4 times less comparing with wagons with conventional cylindrical bearings.
