We offer one of many most in depth lines of specialty Servicing Cost-free roller chain merchandise available to fi t a broad array of specific application requires. Designers can pick out the series that ideal fi ts the unique requirements from the application. These chains really should be specifi ed only when conditions prohibit the use of lubricating oil due to the fact, in general, a properly lubricated regular chain will off er longer existence compared by using a servicing cost-free chain. In some applications having said that lubrication isn?¡¥t attainable and so the use of a self lubricated or sealed roller chain is important.
Standard Properties of Maintenance 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 developed between the pin and bushing as the chain articulates above the sprocket teeth. These chains are rollerless and as a result use thick sectioned powdered metal bushings which can hold a high volume of oil.
PT Form Roller Chains
Oil impregnated powdered metal sintered bushings release oil to your chain joint due to the friction produced in between the pin and bushing since the chain articulates in excess of the sprocket teeth. These chains possess rollers to smooth the action in excess of sprocket teeth. Roller website link plates are one particular dimension thicker to improve power. Side plates and pins have special coatings to stop rust.
C-Type Roller Chains
Very same as over except the side plates are all typical thickness. The power of the CS Form chains is less than the PT Kind but better compared to the SL type. Attachments with conventional dimen-sions may be used for this series and so they’re normally applied on modest materials handling conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains use a rubber seal to keep lubricating grease in although preventing the penetration of grime and various contaminants into the pin/bush-ing bearing place.
Seal Guard Roller Chains
Specifi ed on more substantial pitch roller chains Seal Guard chains use a stainless steel seal to keep lubricating grease in though stopping the penetration of dirt as well as other contaminants in to the pin/bushing bearing region.
