The surface hardness of the tread reaches HCR52-62, and the hardening depth reaches more than 7-10mm (HRC45), ensuring longer impact resistance on the outside and inside of the wheel body. And surface abrasion resistance. In order to adapt to tropical and frigid regions, the high-quality standard floating oil seal and lubriion system formulated by our products enables the sprocket wheel to be completely sealed and free from maintenance under harsh working conditions or climatic conditions (-45℃-120℃).
