Introduce：
Transfer the weight of the machine group to the ground and roll on the tracks. In order to prevent derailment, the rollers should also be able to prevent the track from moving relative to it laterally.
Features：
The new sealing technology is adopted to improve the sealing performance of the bearing system.
The use of integral quenching improves the wear resistance of the wheel body and increases the service life.
