Standard Facts
We offer among the most comprehensive lines of specialty Upkeep Free roller chain solutions out there to fi t a wide array of exclusive application requires. Designers can choose the series that greatest fi ts the unique needs with the application. These chains needs to be specifi ed only when circumstances prohibit the usage of lubricating oil given that, usually, a properly lubricated conventional chain will off er longer existence in contrast having a servicing no cost chain. In some applications having said that lubrication isn?¡¥t feasible and so the use of a self lubricated or sealed roller chain is critical.
General Properties of Upkeep Totally 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 amongst the pin and bushing as the chain articulates more than the sprocket teeth. These chains are rollerless and so use thick sectioned powdered metal bushings which could hold a higher volume of oil.
PT Sort Roller Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint because of the friction produced involving the pin and bushing because the chain articulates over the sprocket teeth. These chains possess rollers to smooth the action more than sprocket teeth. Roller link plates are one size thicker to improve power. Side plates and pins have special coatings to stop rust.
C-Type Roller Chains
Similar as over except that the side plates are all regular thickness. The strength of the CS Variety chains is under the PT Form but higher than the SL type. Attachments with common dimen-sions can be used for this series and therefore they may be usually used on little materials managing conveyors.
P-Ring Chains
Specifi ed on smaller pitch roller chains O-Ring chains use a rubber seal to maintain lubricating grease in whilst stopping 
the penetration of dirt together with other contaminants into the pin/bush-ing bearing location.
Seal Guard Roller Chains
Specifi ed on larger pitch roller chains Seal Guard chains make use of a stainless steel seal to keep lubricating grease in even though preventing the penetration of grime as well as other contaminants in to the pin/bushing bearing spot.
