Bearing Bushes Bronze Bushing Plain Bearing Self-Lubricating Bearing

This type of bushing is widely applied in hoisting machines and other construction machines, automobiles, tractors, trucks, machines tools and some mineral Engines. These are similar to the FB 090 range, except there are solid lubricants embedded into the diamond shaped lubrication indents on the bearing surface, which provide good lubrication conditions at the start up stage, even with a lack of oil. It can be used in construction machinery, gear boxes, automotive clutch parts etc. The bearings are wrapped from a cold formed homogeneous bronze (CuSn6.5) with exceptional material properties. The standard sizes are fitted with diamond shaped lubrication indents in the bearing surface. These indents serve as lubricant reservoirs to rapidly build up a lubrication film at the start of movement and thereafter reduce the running friction. The material is suitable for construction and agricultural machinery applications. Tech. Data Max. Load P Static load 120 N/mm² Elongation 40% Dynamic load 40 N/mm² Temp. -100 ºC~+200 ºC Max.
