Detailed description

Material properties

SF-1B bronze self-lubricating bearing with tin bronze as the base, intermediate sintered bronze spherical powder, surface rolling PTEE and high temperature resistant filling material. It has a very high safety factor, in the continuous work can not stop repair place and the high temperature gas places not suitable. It has been widely used in the metallurgy of iron and steel industry, continuous casting billet rolling, high temperature furnace equipment, cement grouting pump and screw conveyor. It can be in the external combination steel, or in the form of flanging, reach the end, inner hole and friction effect.
