Undercarriage Parts And Bulldozer Assembly For Js200 Excavator Zax 85 Idler
Product Description
The idler (guide wheel) is used to guide the track to rotate correctly and prevent deviation and derailment. The idler (guide wheel) of some hydraulic excavators also functions as a roller, which can increase the contact area between the crawler and the ground and reduce the specific ground pressure. Most of the wheel surfaces of the idler are smooth, with a shoulder ring in the middle as the guide, and the ring surfaces on both sides can support the chain and the roller. The shoulder ring in the middle of the idler (guide wheel) should have sufficient height and the slope on both sides should be small. The smaller the distance between the guide wheel and the nearest roller, the better the guiding performance.

Zax 85 idler adopts the box structure cast by resin sand process. The appearance quality of the wheel body has reasonable mechanical structure performance. The matrix is normalized to obtain good impact resistance, and the medium frequency induction quenching heat treatment of the track surface. Surface hardness To hrc48-54, the depth is not less than 6mm, with wear resistance in harsh conditions
