We offer among the most considerable lines of specialty Upkeep Cost-free roller chain solutions offered to fi t a broad array of distinctive application desires. Designers can pick the series that finest fi ts the specific requirements with the application. These chains need to be specifi ed only when circumstances prohibit using lubricating oil since, on the whole, a well lubricated common chain will off er longer life in contrast that has a upkeep no cost chain. In some applications even so lubrication isn?¡¥t possible and so using a self lubricated or sealed roller chain is important.
General Properties of Maintenance Totally free Roller Chain Items
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil to your chain joint as a result of friction developed in between the pin and bushing because the chain articulates above the sprocket teeth. These chains are rollerless and thus use thick sectioned powdered metal bushings which can hold a substantial volume of oil.
PT Style Roller Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint because of the friction created concerning the pin and bushing since the chain articulates in excess of the sprocket teeth. These chains possess rollers to smooth the action above sprocket teeth. Roller website link plates are a single dimension thicker to improve strength. Side plates and pins have specific coatings to stop rust.
C-Type Roller Chains
Similar as over except the side plates are all common thickness. The strength on the CS Kind chains is less than the PT Style but higher than the SL style. Attachments with typical dimen-sions may be used for this series and thus these are generally utilised on modest material handling conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains utilize a rubber seal to help keep lubricating grease in while stopping the penetration of filth and other contaminants to the pin/bush-ing bearing spot.
Seal Guard Roller Chains
Specifi ed on greater pitch roller chains Seal Guard chains utilize a stainless steel seal to maintain lubricating grease in although preventing the penetration of dirt along with other contaminants into the pin/bushing bearing location.
