ZYB-1B bronze basic bearings are made of tin bronze as the base, sintered bronze spherical powder in the middle, and rolled PTFE and high temperature resistant filling materials on the surface. It has a high safety factor and is especially suitable for places where continuous work cannot be stopped for repairs and where high temperatures cannot be refueled. It is widely used in metallurgical steel industry, billet raceways of continuous casters, high-temperature furnace front equipment, cement grouting pumps and screw conveyors. It can be combined with steel sleeves on the outside, or made into flanging, to achieve the effect of rubbing the end surface and the inner hole at the same time.
