We offer one of many most comprehensive lines of specialty Upkeep Absolutely free roller chain products available to fi t a wide array of specific application desires. Designers can choose the series that finest fi ts the certain demands from the application. These chains needs to be specifi ed only when conditions prohibit using lubricating oil due to the fact, generally, a nicely lubricated regular chain will off er longer life compared with a servicing free chain.

General Properties of Maintenance Free Roller Chain Merchandise
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint as a result of friction produced among the pin and bushing as the chain articulates above the sprocket teeth. These chains are rollerless and hence use thick sectioned powdered metal bushings which can hold a higher volume of oil.
PT Variety Roller Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint due to the friction developed involving 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 link plates are one particular size thicker to improve strength. Side plates and pins have specific coatings to prevent rust.
C-Type Roller Chains
Exact same as above except the side plates are all normal thickness. The power from the CS Form chains is under the PT Form but greater than the SL sort. Attachments with typical dimen-sions may be used for this series and thus they’re often applied on compact material managing conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains employ a rubber seal to maintain lubricating grease in although stopping the penetration of grime and also other contaminants in to the pin/bush-ing bearing region.
Seal Guard Roller Chains
Specifi ed on larger pitch roller chains Seal Guard chains make use of a stainless steel seal to maintain lubricating grease in whilst preventing the penetration of grime and also other contaminants in to the pin/bushing bearing location.
