SF-1B Bronze self-lubricating bearingsDetailed product description：

SF-1B bronze self-lubricating bearing is made of tin bronze as the substrate, sintered with bronze spherical powder in the middle, and rolled with PTEE and high-temperature resistant filling material on the surface. It has a high safety factor and is particularly suitable for places where continuous work cannot be stopped for repairs and places where high temperatures cannot be refueled. At present, it has been widely used in the metallurgical and steel industry, continuous casting machine billet raceway, high-temperature furnace front equipment, cement grouting pump, and screw conveyor. It can be combined with a steel sleeve on the outside or made into a flange to achieve the effect of friction between the end face and the inner hole. ：

SF-1B bronze self-lubricating bearings are available in various forms, including straight sleeve, flanged, thrust washer, sliding plate, and other non-standard components.
Tolerance: It is generally recommended to have a seat hole tolerance of H7 and a shaft diameter tolerance of f7 or h8.
