We offer on the list of most intensive lines of specialty Servicing Absolutely free roller chain solutions offered to fi t a broad array of distinctive application requirements. Designers can opt for the series that finest fi ts the particular desires of your application. These chains really should be specifi ed only when circumstances prohibit using lubricating oil given that, generally, a very well lubricated typical chain will off er longer life in contrast that has a maintenance totally free chain. In some applications having said that lubrication isn?¡¥t probable and so the usage of a self lubricated or sealed roller chain is critical.
General Properties of Upkeep Cost-free Roller Chain Products
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil for the chain joint due to the friction produced concerning the pin and bushing as the chain articulates in excess of the sprocket teeth. These chains are rollerless and so use thick sectioned powdered metal bushings which might hold a high volume of oil.
PT Type Roller Chains
Oil impregnated powdered metal sintered bushings release oil for the chain joint due to the friction created among the pin and bushing because the chain articulates above the sprocket teeth. These chains possess rollers to smooth the action in excess of sprocket teeth. Roller website link plates are 1 size thicker to boost strength. Side plates and pins have exclusive coatings to prevent rust.
C-Type Roller Chains
Identical as above except that the side plates are all typical thickness. The power on the CS Kind chains is less than the PT Type but greater than the SL style. Attachments with typical dimen-sions may be used for this series and as a result they are generally used on small material handling conveyors.
Specifi ed on smaller sized pitch roller chains O-Ring chains utilize a rubber seal to help keep lubricating grease in although preventing the penetration of dirt along with other contaminants into the pin/bush-ing bearing area.
Seal Guard Roller Chains
Specifi ed on bigger pitch roller chains Seal Guard chains use a stainless steel seal to keep lubricating grease in whilst avoiding the penetration of filth as well as other contaminants in to the pin/bushing bearing place.
