Product Information
 
  

E330 track roller    

1. The Idler body is a casting part, and the wheel body has durability and rust resistance after special heat treatment.

 

2. High hardness wear-resistant chrome aluminum alloy floating oil seal and elastic rubber O-ring.

  

3.The Idler with the hardness of the wheel body diameter and the design of the guide shaft and the reasonable outer diamete to increases the wear life.


4. All of leading shaft, copper bushing and sealing parts are passed through the fully automatic production system, and the precision is controlled by the numerical control computer to ensure the accuracy of the shaft.

Track rollers are mainly composed of value shaft, wheel body, shaft sleeve, floating oil seal seat, screw plug, ring, floating oil seal, annular ring, pin and so on. It is located between the lower surface of the left and right beams of the chassis and supports the track. Depending on the tonnage of the excavator, there are usually 5-10 on one side.


Track rollers can be divided into unilateral rollers and bilateral rollers according to the structure, using sliding bearings and rolling shafts. The supporting rims are quenched and their hardness reaches 355-440 HB. In the trolley frame, the supporting wheels, especially when the partition is installed to improve the rigidity, some cavities formed are easily blocked by the soil and hinder the supporting wheels from rotating; when running on the soaked soil, the supporting wheels are also easily blocked wheel.

The processing accuracy of E330 track roller axles is relatively high. Generally, CNC machine tools are required to meet the requirements. The material is mostly 50Mn2. After processing, quenching heat treatment is also required, and the hardness reaches about HRC42. They are usually supported by sliding bearings and dust-proof with floating oil seals.

  

The advantage of doing this is that generally only one butter is needed during an overhaul period, which simplifies the usual maintenance of the excavator.
