AST850SM Metric Series 30.000 Millimeter (mm) Nominal Shaft Diameter (d) and 34.00 Millimeter (mm) Nominal Bearing Outside Diameter (Do) Metal Backed Bronze Powder and Graphite Bushing

The AST850SM Series Bushings are metal backed with bronze alloy graphite oil-less bushings. They are composite multi-layer bushings composed of special sintered material used as sliding surfaces and steel material as backing metal. Sintered layers are of a special copper-nickel alloy containing uniformly dispersed solid lubricant, the main component of which is graphite. The solid lubricants will be released at the bushing surface as wear occurs, this will ensure have lower coefficient of friction during operation. In addition, these sintered layers have been processed by the oil impregnation treatment.
