Standard Facts
We offer among the list of most intensive lines of specialty Servicing Cost-free roller chain merchandise readily available to fi t a wide array of specific application demands. Designers can pick out the series that finest fi ts the unique demands of the application. These chains must be specifi ed only when circumstances prohibit the use of lubricating oil considering the fact that, on the whole, a well lubricated conventional chain will off er longer existence in contrast with a servicing absolutely free chain. In some applications even so lubrication isn?¡¥t attainable and so the use of a self lubricated or sealed roller chain is necessary.
Common Properties of Maintenance Free of charge 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 involving the pin and bushing since the chain articulates above the sprocket teeth. These chains are rollerless and so use thick sectioned powdered metal bushings which could hold a higher volume of oil.
PT Type Roller Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint because of the friction created amongst the pin and bushing since the chain articulates in excess of the sprocket teeth. These chains possess rollers to smooth the action more than sprocket teeth. Roller link plates are 1 dimension thicker to boost strength. Side plates and pins have particular coatings to prevent rust.
C-Type Roller Chains
Exact same as over except the side plates are all common thickness. The strength of the CS Type chains is less than the PT Type but better compared to the SL form. Attachments with normal dimen-sions may be used for this series and as a result they are really often used on compact material managing conveyors.
P-Ring Chains
Specifi ed on smaller sized pitch roller chains O-Ring chains utilize a rubber seal to keep lubricating grease in though stopping the penetration of dirt and various contaminants into the pin/bush-ing bearing location.
Seal Guard Roller Chains
Specifi ed on larger pitch roller chains Seal Guard chains utilize a stainless steel seal to maintain lubricating grease in even though preventing the penetration of grime together with other contaminants into the pin/bushing bearing spot.
