Among all four-wheel and track consumables, the carrier roller (top roller) ranks among the most searched items by overseas distributors, repair workshops and fleet owners. Alongside track roller, idler, sprocket and track chain assembly, these undercarriage components are the best-selling aftermarket wear parts for excavators and bulldozers across South Africa, Brazil, Southeast Asia, the Middle East and Latin America.

All carrier rollers and track rollers adopt high-frequency quenching heat treatment. The sealed floating seal design prevents oil leakage under harsh environments. Our product lineup covers excavators CAT320, PC200, SK200, ZX200 and bulldozers D6D, D7G, D155, SD16, SD22. We accept small trial orders and OEM customization for global importers and spare parts wholesalers.

As large volumes of second-hand excavators and bulldozers enter maintenance cycles in emerging markets, demand for four-wheel and track undercarriage parts keeps rising. We maintain stable stock and short lead time to help overseas customers reduce machine downtime and cut maintenance expenditure.
