SF-1B copper-based non-oil bearing, bronze self-lubricating bearings are bronze matrix, sintered bronze spherical powder, the surface rolling PTEE and high temperature filler material together. It has a very high safety factor, especially for the continuous work can not be shut down to repair the place and can not refuel hot place. Has been widely used in the metallurgical steel industry, continuous casting billet groove, the high-temperature furnace blast furnace equipment, cement grouting pumps and screw conveyors. It can be a combination of the external steel sleeve, or made into cuff, to face, bore the same time, the friction results.
