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 surface hardness of the supporting wheel is HRC45-55. The depth is 3mm-6mm.
