We offer one of several most extensive lines of specialty Servicing Free of charge roller chain items available to fi t a broad array of specific application desires. Designers can decide on the series that very best fi ts the certain wants in the application. These chains needs to be specifi ed only when conditions prohibit the use of lubricating oil since, on the whole, a very well lubricated conventional chain will off er longer lifestyle compared using a maintenance absolutely free chain. In some applications however lubrication isn?¡¥t probable and so the usage of a self lubricated or sealed roller chain is necessary.
Common Properties of Upkeep Totally free Roller Chain Goods
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil for the chain joint because of the friction developed among the pin and bushing since the chain articulates in excess of the sprocket teeth. These chains are rollerless and hence use thick sectioned powdered metal bushings which might hold a substantial volume of oil.
PT Sort Roller Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint because of the friction formulated in between the pin and bushing since the chain articulates over the sprocket teeth. These chains possess rollers to smooth the action more than sprocket teeth. Roller link plates are a single size thicker to improve strength. Side plates and pins have specific coatings to avoid rust.
C-Type Roller Chains
Very same as over except that the side plates are all common thickness. The power with the CS Style chains is less than the PT Kind but better compared to the SL sort. Attachments with common dimen-sions may be used for this series and thus they are really typically employed on tiny material dealing with conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains make use of a rubber seal to help keep lubricating grease in when preventing the penetration of dirt and also other contaminants in to the pin/bush-ing bearing location.
Seal Guard Roller Chains
Specifi ed on bigger pitch roller chains Seal Guard chains employ a stainless steel seal to help keep lubricating grease in though avoiding the penetration of grime as well as other contaminants to the pin/bushing bearing location.
