527-2758 527-2758 E305E2 E305E Steel 50MN Mini Excavator Undercarriage Parts Track Rollers
The function of the supporting wheel is to transmit the weight of the locomotive group to the ground and roll on the track. To prevent derailment, the supporting wheels should also be able to prevent the track from moving laterally relative to it.
Supporting wheels often work in mud, water, ash, and sand, and withstand strong impacts. The working conditions are extremely harsh, and the wheel flanges are easily worn.
The requirements for the supporting wheel are: wear-resistant rim, reliable bearing sealing, and low rolling resistance.
