Oil impregnated powdered metal sintered bushings release oil on the chain joint due to the friction created between the pin and bushing since the chain articulates above the sprocket teeth. These chains are rollerless and as a result use thick sectioned powdered metal bushings which might hold a large volume of oil.
PT Sort Roller Chains
