ZYB-2X boundary lubrication bearing is based on steel plate, sintered spherical bronze powder in the middle, surface-rolled modified polyoxymethylene (POM), and contains oil storage pits. It is suitable for places with low speed and medium load under normal temperature conditions, replacing traditional copper sleeves to reduce costs and extend service life. When used on a rolling mill, it can save the refueling frequency and simplify the replacement procedure. This product has been widely used in automotive sites, forging machine tools, metallurgical mining machinery, engineering machinery, water and electricity, steel rolling industries and other fields.
