It specializes in various kinds oilless bearing in Zhejiang Jiashan Roncan Slide bearing Co., ld. The company is located in the economic development zone of ganyao Jiashan Zhejiang China, very convenient. Various kinds without oil bearing annual output have been produced more than 20 million sets. Mainly produces: SF-1(DU) oil-free bush, SF-2(DX) boundary lubricating bush, JF-800 bimetals coiled bearings, FZ steel ball retainers, JDB(500#) solid lubricating bearings, FD PTFE straps, FR PTFE soft strapped bearings, FB090 bronze bearings and sliding bearings.

It's made of bronze or iron powder, mold pressed under high pressure and then sintered under high temperature, and oil is soaked into the homogeneously spread tiny pores of the metal under vacuum. It's used in domestic electric appliances, electric tools, and textiles machinery.

The base material for sintered parts such as sliding bearings or other formed parts are iron, bronze, iron with bronze and other metal in powder form. This powder is formed under high pressure in dies into a temperature, which is just below the melting point. According to the work condition, the bearings can impregnate with different oil or solid lubricants for the self-lubricating. Sintered self-lubricating bearings are the ideal and economical solution for applications where lubrication is difficult or lubrication could not be applied.
