The AST650 series bushing material consists of strong cast bronze as a base material and is combined with solid lubricants. This kind of material provides a maintenance-free solution and is particularly good for high load and intermittent of oscillating motion.
AST090 Series bushing material is provided with a uniform pattern of indents which act as grease reservoirs. The ASTT090 Series supplies lubricant through holes instead of indents which provide larger amounts of lubricant to be incorporated during operation.
The AST800 material is consist of the bronze powder and steel backed material, and the AST850 metal backed bronze with graphite lined bushing material, sintered layers are of special copper alloy containing uniformly dispersed solid lubricants. This series materials is supply for dry/marginal lubricated solutions.
Our range of oil-impregnated sintered bronze bushings is intended for use in maintenance-free operations, under moderately high speeds and low loads.
AST has nearly 1,800 bushing models that are made of metallic materials and are self-lubricating. They are broken down into the following series. Click on each to learn more:
