General Info
We offer among the most in depth lines of specialty Upkeep Absolutely free roller chain solutions available to fi t a broad array of distinctive application requires. Designers can select the series that very best fi ts the specific requirements on the application. These chains need to be specifi ed only when conditions prohibit the usage of lubricating oil since, in general, a effectively lubricated standard chain will off er longer life compared using a maintenance free of charge chain. In some applications having said that lubrication isn?¡¥t probable and so the usage of a self lubricated or sealed roller chain is critical.
Standard Properties of Maintenance Absolutely free Roller Chain Goods
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint due to the friction designed between the pin and bushing as the chain articulates over the sprocket teeth. These chains are rollerless and as a result use thick sectioned powdered metal bushings which can hold a large volume of oil.
PT Sort Roller Chains
Oil impregnated powdered metal sintered bushings release oil for the chain joint as a result of friction designed involving 
the pin and bushing as the chain articulates more than the sprocket teeth. These chains possess rollers to smooth the action above sprocket teeth. Roller hyperlink plates are one particular size thicker to increase power. Side plates and pins have exclusive coatings to stop rust.
C-Type Roller Chains
Identical as over except that the side plates are all typical thickness. The strength in the CS Sort chains is less than the PT Sort but greater than the SL sort. Attachments with typical dimen-sions can be used for this series and therefore they can be frequently employed on little materials handling conveyors.
P-Ring Chains
Specifi ed on smaller sized pitch roller chains O-Ring chains employ a rubber seal to help keep lubricating grease in whilst stopping the penetration of grime as well as other contaminants in to the pin/bush-ing bearing spot.
Seal Guard Roller Chains
Specifi ed on bigger pitch roller chains Seal Guard chains make use of a stainless steel seal to keep lubricating grease in while avoiding the penetration of filth and other contaminants in to the pin/bushing bearing area.
