Suitable for low/middle load, middle velocity application #500F is oilless bearing material, based on cast iron base with solid lubricants embedded therein. l Self-lubricated and maintenance-free, suitable for low/middle load, middle velocity application. l Exert excellent wear resistance where it's difficult of lubricating film to be formed during reciprocating, oscillating or frequently intermittent operation. lIt's a cost-saving solution compared with copper alloy based bearings
