We offer on the list of most in depth lines of specialty Upkeep Free roller chain products readily available to fi t a broad array of special application demands. Designers can opt for the series that best fi ts the unique needs with the application. These chains really should be specifi ed only when circumstances prohibit the use of lubricating oil since, usually, a nicely lubricated regular chain will off er longer existence compared by using a servicing cost-free chain. In some applications on the other hand lubrication isn?¡¥t probable and so the use of a self lubricated or sealed roller chain is critical.
Basic Properties of Servicing No cost Roller Chain Solutions
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil for the chain joint as a result of friction developed among the pin and bushing since the chain articulates in excess of the sprocket teeth. These chains are rollerless and as a result use thick sectioned powdered metal bushings which can hold a higher volume of oil.
PT Sort Roller Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint because of the friction developed concerning the pin and bushing as 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 one size thicker to boost strength. Side plates and pins have exclusive coatings to avoid rust.
C-Type Roller Chains
Similar as over except that the side plates are all regular thickness. The power from the CS Kind chains is lower than the PT Form but greater than the SL type. Attachments with conventional dimen-sions can be utilized for this series and so these are usually made use of on tiny material handling conveyors.
Specifi ed on smaller sized pitch roller chains O-Ring chains utilize a rubber seal to help keep lubricating grease in whilst stopping the penetration of grime and various contaminants in to the pin/bush-ing bearing place.
Seal Guard Roller Chains
Specifi ed on greater pitch roller chains Seal Guard chains use a stainless steel seal to maintain lubricating grease in whilst stopping the penetration of filth and also other contaminants to the pin/bushing bearing region.
