Common Information and facts
We offer one of many most considerable lines of specialty Upkeep Absolutely free roller chain products readily available to fi t a broad array of specific application requires. Designers can pick out the series that greatest fi ts the particular requirements in the application. These chains ought to be specifi ed only when situations prohibit using lubricating oil considering the fact that, generally, a nicely lubricated normal chain will off er longer daily life in contrast with a upkeep free chain. In some applications nevertheless lubrication isn?¡¥t attainable and so using a self lubricated or sealed roller chain is critical.
General Properties of Maintenance Free Roller Chain Solutions
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint as a result of friction designed involving the pin and bushing because the chain articulates in excess of the sprocket teeth. These chains are rollerless and as a result use thick sectioned powdered metal bushings which could hold a substantial volume of oil.
PT Type Roller Chains
Oil impregnated powdered metal sintered bushings release oil to your chain joint because of the friction formulated 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 link plates are one dimension thicker to increase strength. Side plates and pins have special coatings to prevent rust.
C-Type Roller Chains
Similar as over except that the side plates are all common thickness. The power of the CS Form chains is less than the PT Form but better than the SL type. Attachments with standard dimen-sions may be used for this series and therefore they’re typically used on modest materials dealing with conveyors.
P-Ring Chains
Specifi ed on smaller sized pitch roller chains O-Ring chains employ a rubber seal to keep lubricating grease in even though stopping the penetration of filth and various contaminants to the pin/bush-ing bearing location.
Seal Guard Roller Chains
Specifi ed on greater pitch roller chains Seal Guard chains utilize a stainless steel seal to help keep lubricating grease in though avoiding the penetration of grime and other contaminants into the pin/bushing bearing region.
