We offer on the list of most substantial lines of specialty Servicing Cost-free roller chain merchandise available to fi t a broad array of distinctive application desires. Designers can choose the series that best fi ts the certain requires in the application. These chains ought to be specifi ed only when circumstances prohibit the usage of lubricating oil due to the fact, usually, a nicely lubricated standard chain will off er longer lifestyle in contrast that has a maintenance totally free chain. In some applications having said that lubrication isn?¡¥t feasible and so the usage of a self lubricated or sealed roller chain is critical.
Common Properties of Servicing Free Roller Chain Products
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint due to the friction designed involving the pin and bushing since the chain articulates above the sprocket teeth. These chains are rollerless and consequently use thick sectioned powdered metal bushings which could hold a high volume of oil.
PT Type Roller Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint due to the friction produced involving the pin and bushing because the chain articulates more than the sprocket teeth. These chains possess rollers to smooth the action over sprocket teeth. Roller link plates are 1 dimension thicker to increase strength. Side plates and pins have unique coatings to avoid rust.
C-Type Roller Chains
Exact same as over except the side plates are all regular thickness. The strength on the CS Kind chains is lower than the PT Type but higher compared to the SL sort. Attachments with conventional dimen-sions can be used for this series and thus they may be often utilised on little material dealing with conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains use a rubber seal to keep lubricating grease in whilst stopping the penetration of grime and also other contaminants into the pin/bush-ing bearing area.
Seal Guard Roller Chains
Specifi ed on greater pitch roller chains Seal Guard chains use a stainless steel seal to keep lubricating grease in although avoiding the penetration of filth together with other contaminants into the pin/bushing bearing area.
