SF-2S does not have the oil lubrication bearing, is the SF-2 advanced version product, take the steel back as the substrate, among agglutinates the ball gun metal powder, the superficial rolling and includes the lipophilic textile fiber and the special lubricant polymer material by the acetal resin. The overseas same product is the DS bearing, the dry friction and the few oil lubrication situation which under the adaption normal temperature condition works, has the friction coefficient lowly, the wear-resisting performance is good, does not have the oil condition lubrication the merit. At present the product has applied the situation which in the pivoting motion, is easy to wear, is easy to corrode, like, bulldozer, printing machine, coal mining machine and crane, driving work high above the ground machine situation and so on volume field machine.
