We offer one of the most extensive lines of specialty Upkeep Free roller chain goods obtainable to fi t a wide array of specific application requires. Designers can pick out the series that greatest fi ts the certain demands of the application. These chains really should be specifi ed only when circumstances prohibit the usage of lubricating oil because, generally, a properly lubricated typical chain will off er longer existence compared with a maintenance free chain. In some applications nevertheless lubrication isn?¡¥t probable and so using a self lubricated or sealed roller chain is important.
Basic Properties of Maintenance Absolutely free Roller Chain Products
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint due to the friction developed amongst 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 may hold a high volume of oil.
PT Sort Roller Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint due to the friction created amongst the pin and bushing as the chain articulates over the sprocket teeth. These chains possess rollers to smooth the action in excess of sprocket teeth. Roller website link plates are one dimension thicker to improve strength. Side plates and pins have exclusive coatings to prevent rust.
C-Type Roller Chains
Similar as over except that the side plates are all regular thickness. The strength of the CS Sort chains is lower than the PT Form but greater compared to the SL form. Attachments with typical dimen-sions may be used for this series and thus they’re generally applied on compact material handling conveyors.
Specifi ed on smaller sized pitch roller chains O-Ring chains employ a rubber seal to keep lubricating grease in even though avoiding the penetration of filth together with other contaminants into the pin/bush-ing bearing location.
Seal Guard Roller Chains
Specifi ed on bigger pitch roller chains Seal Guard chains make use of a stainless steel seal to help keep lubricating grease in whilst preventing the penetration of dirt together with other contaminants into the pin/bushing bearing area.
