Basic Properties of Maintenance Absolutely free Roller Chain Goods
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil for the chain joint as a result of friction designed concerning the pin and bushing as the chain articulates more than the sprocket teeth. These chains are rollerless and as a result use thick sectioned powdered metal bushings which might hold a substantial volume of oil.
PT Kind Roller Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint as a result of friction designed among the pin and bushing because the chain articulates in excess of the sprocket teeth. These chains possess rollers to smooth the action over sprocket teeth. Roller website link plates are 1 size thicker to boost strength. Side plates and pins have particular coatings to prevent rust.
C-Type Roller Chains
Exact same as above except the side plates are all regular thickness. The strength on the CS Sort chains is lower than the PT Kind but better than the SL style. Attachments with conventional dimen-sions can be utilized for this series and therefore these are usually utilized on modest materials dealing with conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains utilize a rubber seal to keep lubricating grease in when avoiding the penetration of dirt and also other contaminants into the pin/bush-ing bearing spot.
Seal Guard Roller Chains
