Product Description


The function of the roller is to transfer the weight of the locomotive to the ground and roll on the track. In order to prevent derailment, the roller should also be able to prevent the track from moving laterally relative to it.
The roller often works in muddy sand, and it is subjected to strong impact. The working conditions are extremely bad and the rim is easy to wear. The requirements for the roller are: rim wear, reliable bearing seal, and low rolling resistance.
