We offer one of many most extensive lines of specialty Maintenance Free of charge roller chain merchandise obtainable to fi t a wide array of distinctive application requires. Designers can pick out the series that best fi ts the unique requires of the application. These chains needs to be specifi ed only when conditions prohibit using lubricating oil since, usually, a well lubricated conventional chain will off er longer lifestyle in contrast using a upkeep free chain. In some applications having said that lubrication isn?¡¥t feasible and so the use of a self lubricated or sealed roller chain is important.
General Properties of Upkeep Free Roller Chain Products
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint as a result of friction created among the pin and bushing since the chain articulates more than 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 Type Roller Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint due to the friction developed concerning the pin and bushing as the chain articulates over the sprocket teeth. These chains possess rollers to smooth the action above sprocket teeth. Roller link plates are a single dimension thicker to boost power. Side plates and pins have special coatings to prevent rust.
C-Type Roller Chains
Identical as over except the side plates are all regular thickness. The power in the CS Form chains is less than the PT Sort but better compared to the SL form. Attachments with normal dimen-sions can be used for this series and therefore they’re usually used on compact material dealing with conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains employ a rubber seal to keep lubricating grease in whilst preventing the penetration of dirt and also other contaminants into 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 even though stopping the penetration of dirt along with other contaminants to the pin/bushing bearing region.
