General Information and facts
We offer among the list of most considerable lines of specialty Upkeep Free roller chain merchandise available to fi t a wide array of special application needs. Designers can pick the series that best fi ts the distinct requirements from the application. These chains should be specifi ed only when situations prohibit the use of lubricating oil since, generally, a effectively lubricated regular chain will off er longer life in contrast that has a maintenance cost-free chain. In some applications having said that lubrication isn?¡¥t possible and so using a self lubricated or sealed roller chain is necessary.
Standard Properties of Servicing Free of charge Roller Chain Products
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint due to the friction created in between the pin and bushing since the chain articulates over the sprocket teeth. These chains are rollerless and as a result use thick sectioned powdered metal bushings which could hold a large volume of oil.
PT Style Roller Chains
Oil impregnated powdered metal sintered bushings release oil to your chain joint due to the friction designed involving the pin and bushing since the chain articulates over the sprocket teeth. These chains possess rollers to smooth the action in excess of sprocket teeth. Roller hyperlink plates are one particular size thicker to boost power. Side plates and pins have distinctive coatings to stop rust.
C-Type Roller Chains
Exact same as above except that the side plates are all normal thickness. The power from the CS Type chains is less than the PT Form but greater 
than the SL sort. Attachments with normal dimen-sions can be utilized for this series and therefore these are often made use of on modest material dealing with conveyors.
P-Ring Chains
Specifi ed on smaller sized pitch roller chains O-Ring chains make use of a rubber seal to help keep lubricating grease in even though avoiding the penetration of dirt along with other contaminants into the pin/bush-ing bearing place.
Seal Guard Roller Chains
Specifi ed on greater pitch roller chains Seal Guard chains employ a stainless steel seal to maintain lubricating grease in although preventing the penetration of grime as well as other contaminants into the pin/bushing bearing spot.
