We offer one of many most considerable lines of specialty Upkeep No cost roller chain items readily available to fi t a wide array of exclusive application requires. Designers can pick out the series that very best fi ts the individual wants of the application. These chains ought to be specifi ed only when situations prohibit the use of lubricating oil given that, usually, a well lubricated regular chain will off er longer lifestyle compared which has a servicing free of charge chain. In some applications nonetheless lubrication isn?¡¥t possible and so the use of a self lubricated or sealed roller chain is critical.
Basic Properties of Upkeep Free Roller Chain Products
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint as a result of friction developed involving the pin and bushing since the chain articulates over the sprocket teeth. These chains are rollerless and hence use thick sectioned powdered metal bushings which could hold a substantial volume of oil.
PT Kind Roller Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint due to the friction formulated among the pin and bushing since the chain articulates above the sprocket teeth. These chains possess rollers to smooth the action more than sprocket teeth. Roller link plates are one particular size thicker to increase power. Side plates and pins have unique coatings to stop rust.
C-Type Roller Chains
Same as above except the side plates are all typical thickness. The strength on the CS Form chains is less than the PT Form but greater compared to the SL type. Attachments with regular dimen-sions can be used for this series and thus they are really frequently utilized on modest material dealing with conveyors.
Specifi ed on smaller sized pitch roller chains O-Ring chains use a rubber seal to maintain lubricating grease in while preventing the penetration of grime and also other contaminants to the pin/bush-ing bearing region.
Seal Guard Roller Chains
Specifi ed on more substantial pitch roller chains Seal Guard chains make use of a stainless steel seal to maintain lubricating grease in although stopping the penetration of filth and other contaminants to the pin/bushing bearing location.
