Bunting sintered bronze stock bearings have long conformed to ASTM chemical and physical properties, and are the first to include all ASTM standard sizes to ASTM recommended dimensions and tolerances
After forming, sintering and sizing, the bearings are vacuum impregnated with SAE 30 oil that provides lubricant which is metered from the bearing to the shaft during rotation
Standard off-the-shelf oil impregnated bronze bearings should function satisfactorily in temperatures ranging from 10°F to 220°F
