FU-2 base oil bearing, is a kind of iron base powder metallurgical products, due to the role of oil, can prevent the phenomenon of biting. In the case of low load, the wear resistance of copper powder metallurgy can be similar. The products are widely used in textile machinery, automobile and motorcycle shock absorber device and FU-2 iron base oil-impregnated sintered powder bearing is a occlusion-proof Bush due to reserving oil in the opening. It has similar characteristics during low load. It is widely used to sliding parts of textile machine, automobile and motorcycle damper and electric tools. It can be used as base for guiding shaft shrink sleeve. Electric tool sliding parts. The base can be used as a guide in the use of the positioning sleeve static environment.
