idler pc200

The idler pc200, which is also called idler group, idler assy, front idler or idler wheel, is one part of undercarriage parts for crawler heavy equipments such as excavator, bulldozer, crane, drilling machine etc. The idler pc200 is made of idler shell, shaft, brackets, Bi-metallic Bearings and seal group. It is made by casting or forging, machining, heat treatment, assembly, painting etc. The quality and working life depends on the quality of raw steels, the hardness of rail surface, the depth of hardness layer, the quality of seal group etc. The misalignment of the idler excavator has a serious impact on other parts of the walking mechanism, so we need to adjust the gap between the guide wheel guide plate and the track frame to achieve the purpose of extending the life of the walking mechanism. When adjusting the gap, pay attention to use the gasket between the guide plate and the bearing to correct it. If the gap is large, remove the gasket; if the gap is small, add a gasket.
