Product Details

Materials: Brass or bronze + graphite

solid mosaic bearing is versatile basic products, whether high pressure, low pressure, high temperature, low temperature, oil-lubricated, non-lubricated or water lubrication, can adapt. Product matrix is a high-strength brass, copper sleeve than double the hardness, wear resistance more than double, so in the metallurgical industry, continuous casting machines, rolling mills, conveyors can be used. Also used in plastic injection molding machine clamping mechanism, extrusion mechanism, high-voltage automatic switches, construction lifting machinery support site, and water was Project arc door support, pulley and gear wheel parts. There are paper machine drying tunnel, the car dies, the ship weighed anchor and other sliding parts. Available form; straight sets, flange bushings, thrust washers, skateboards and other non-standard parts, etc. Tolerance: Recommend housing tolerance H7, bearing tolerance f7 or h8..
