Caterpillar Idler
The Caterpillar idler, like its name, has the function of guiding and steering. In the equipment for steering, the spring assembly of the chassis system will control the operation of the idler, in order to avoid the idler can’t work properly. After the equipment stops, you should clean up the accumulation of soil and bits on the idler, to avoid entering into the internal bearings, in the equipment up and down the slope should be avoided to guide the wheel towards the back, this is easy to let the chain derailment. The wheel body of Caterpillar idler adopts a roller forging process, the wheel surface is tough enough after long time of forging, and the wheel axle is treated with high accuracy, basically not much need to replace this part. And the use of a lightweight design, the overall performance of the equipment have been significantly improved, and lower the transportation costs.
Terris Caterpillar idlers are designed with reference to a number of manufacturers’ processes to create a product that is unique to Terris. After roll forging the wheel body, we apply a specific process to the track surface of the Caterpillar idler, which solves a series of problems such as wheel surface collapse, wheel surface cracking, etc., and prolongs the service life of the wheel. For the treatment of axle, bushing and bracket, we have also made a lot of technical research and development improvements through the study of the characteristics of Caterpillar’s idler, and then produced reliable products that do not leak oil, do not break the axle, and are wear-resistant and durable! We have been recognized by the OEMS of the host equipment manufacturers in the industry for our quality control.
