The idler is used to support the track shoe Assy and guide the winding of the track shoe Assy. The rim of the idler can jam the outer edge of the track link to prevent lateral shedding, and tighten the track through the tensioning buffer connected to mitigate the impact force from the ground to the frame.


The idler is welded with steel plate and its radial section is box shaped.


Bulldozer idler surface is generally yellow paint.

Materials and technology:

The body material of idler is generally 50Mn, 40Mn2. The main process is casting or forging, mechanical processing, after which shall be heat treatment. The hardness of the idler surface after quenching should reach HRC45~52, so as to increase the wear resistance of the idler surface. Idler shaft machining precision with higher requirement, generally need CNC machine tools for processing to meet the requirements. Material 40Mn2, after processing, also need to carry out quenching heat treatment, hardness up to HRC60 or so.

Frequently asked questions and analysis

It is proved by inspection that the wear of the idler shaft and the damage of the sleeve of the sliding bearing are caused by the deterioration of the lubrication state between the idler shaft and the sleeve of the sliding bearing, and the transformation of boundary lubrication into partial dry friction state. In normal operation, there is a certain gap between the idler shaft and the sleeve of the sliding bearing and oil film exists, forming liquid lubrication, which generates less heat and is carried away by the lubricating oil, so that the working temperature of the bearing is in a normal state. If the lubrication state is formed of bearing sleeve and shaft deteriorates and part of dry friction state, the friction power consumption increases sharply and a large amount of friction heat is generated. When the temperature exceeds the melting point of the alloy on the sleeve surface, it will begin to melt until it is completely burned out.
