The supporting wheel is one of the four-wheel belts of the crawler-type construction machinery chassis. Its main function is to support the weight of the excavator and bulldozer, so that the track moves along the wheels. Based on precise accessories, careful heat treatment and wear-resistant oil seal system, good internal oil circulation system ensures the service life of the wheel. Forged wheel housings achieve excellent internal material fiber flow distribution.

The drag chain wheel is used to prevent the crawler from sagging and falling off when the crawler is walking, and can reduce its up and down vibration function. Based on precise accessories, careful heat treatment and wear-resistant oil seal system, good internal oil circulation system ensures the service life of the wheel. The surface hardness of the supporting sprocket is HRC45-55, and the depth is 3-6mm.
