Description
Boundary lubrication bushing
This is a steel-based, sintered bronze spherical powder as interlayer and overlaid by a layer of POM, the surface of which is provided with oil indentations.
The thickness of the plastics layer is about 0.5mm.
A trace of oil or grease may be utilized and may work successfully under heavy load with oscillating motion and those which start and stop frequently under load.
Moreover, it is of low cost and long life. This kind of material is now widely used as bushes in chassis of automobiles, forging presses, metallurgical and mining machines, civil engineering machines, hydroelectric industrial machines and steel strip cold rolling machines.
It is a lead-free product.
Marginally lubricated bushings for grease or oil lubricated applications · Standard parts contain grease indents in the sliding layer.
Carbon Steel + Copper Powder + POM
It’s used in vehicle chassis, forming machine tools, steel metallurgical machinery, mineral mountain machinery, hydraulic industry and rolling steel industry, etc.
