The position of the excavator track roller in the excavator

1.Roller axles: This is the core component of the supporting wheel structure, which carries the weight of the entire supporting wheel and the load during excavator operation. The support wheel axle is usually fixed at the lower part of the excavator track frame to ensure that the support wheel can stably support the excavator.excavator bottom roller for E215C

2.Shaft sleeve: The shaft sleeve is installed on the supporting axle, which plays a role in protecting the supporting axle and reducing wear. There is usually a certain gap between the shaft sleeve and the supporting wheel shaft, so that the supporting wheel can rotate flexibly.

3.Thrust ring (some structures have): In some support wheel structures, the thrust ring is fitted onto the support wheel shaft and located on one side of the shaft sleeve. Its main function is to prevent the support wheel axle from shifting in the axial direction, thereby enhancing the stability of the support wheel.excavator bottom roller for E215C

4.Sealing ring: The sealing ring is an important component of the supporting wheel structure, which is installed on the supporting wheel shaft and located between the shaft sleeve and the thrust ring (if any). The main function of the sealing ring is to prevent the leakage of lubricating oil inside the supporting wheel, and to prevent impurities such as mud and water from entering the interior of the supporting wheel, thereby protecting the internal structure of the supporting wheel.

5.Excavator track roller: The supporting wheel body is the outermost part of the supporting wheel, which is fitted on the shaft sleeve and covers the sealing ring and thrust ring (if any). The supporting wheel body usually has a certain thickness and strength to withstand the impact and load during excavator operation. At the same time, there are flanges on both sides of the supporting wheel body to clamp the track chain and prevent the track from derailing.excavator bottom roller for E215C
