We offer one of the most intensive lines of specialty Upkeep Free of charge roller chain solutions obtainable to fi t a wide array of exclusive application demands. Designers can pick the series that ideal fi ts the particular needs on the application. These chains really should be specifi ed only when circumstances prohibit the usage of lubricating oil considering the fact that, normally, a very well lubricated normal chain will off er longer daily life compared by using a upkeep absolutely free chain. In some applications nonetheless lubrication isn?¡¥t probable and so the usage of a self lubricated or sealed roller chain is important.
Standard Properties of Servicing Free Roller Chain Goods
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint as a result of friction formulated between the pin and bushing because the chain articulates more than the sprocket teeth. These chains are rollerless and so use thick sectioned powdered metal bushings which could hold a large volume of oil.
PT Form Roller Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint due to the friction developed involving the pin and bushing because the chain articulates above the sprocket teeth. These chains possess rollers to smooth the action above sprocket teeth. Roller hyperlink plates are 1 size thicker to boost power. Side plates and pins have particular coatings to stop rust.
C-Type Roller Chains
Very same as over except the side plates are all normal thickness. The power on the CS Type chains is less than the PT Form but higher compared to the SL form. Attachments with common dimen-sions may be used for this series and so they can be typically employed on tiny materials handling conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains employ a rubber seal to keep lubricating grease in though preventing the penetration of grime and various contaminants in to the pin/bush-ing bearing spot.
Seal Guard Roller Chains
Specifi ed on bigger pitch roller chains Seal Guard chains employ a stainless steel seal to maintain lubricating grease in whilst avoiding the penetration of dirt as well as other contaminants into the pin/bushing bearing region.
