Introduction

SF-1B Bronze Bushing is based on tin Bronze as the base, the middle sintered Bronze spherical powder, the surface rolling PTEE and high temperature filled material. It has a high safety factor, can not stop working in the continuous repair of high-temperature places and can not be particularly suitable for refueling places. At present, the product has been widely used in the metallurgical steel industry, continuous casting machine billet raceway, high-temperature furnace furnace equipment, cement grouting pump and screw conveyor. It can be combined in the external steel sleeve, can also be made into flanging, to the end, the hole at the same time the effect of friction. Sliding bearing part of the bridge, is the use of SF-1B wear-resistant layer of thick PTFE products to replace the plate. Up to 130N / mm² load-bearing requirements.
