We offer one of several most intensive lines of specialty Maintenance Cost-free roller chain items readily available to fi t a broad array of exclusive application demands. Designers can choose the series that ideal fi ts the particular needs with the application. These chains must be specifi ed only when conditions prohibit using lubricating oil considering that, usually, a well lubricated typical chain will off er longer existence compared using a servicing free chain. In some applications nonetheless lubrication isn?¡¥t probable and so the use of a self lubricated or sealed roller chain is important.
Common Properties of Servicing No cost Roller Chain Merchandise
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint because of the friction formulated concerning the pin and bushing as the chain articulates in excess of the sprocket teeth. These chains are rollerless and therefore 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 on the chain joint as a result of friction created in between the pin and bushing because the chain articulates in excess of the sprocket teeth. These chains possess rollers to smooth the action above sprocket teeth. Roller link plates are 1 dimension thicker to increase strength. Side plates and pins have specific coatings to stop rust.
C-Type Roller Chains
Same as over except the side plates are all conventional thickness. The strength with the CS Variety chains is under the PT Kind but better compared to the SL style. Attachments with conventional dimen-sions may be used for this series and so they’re normally employed on small material managing conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains utilize a rubber seal to maintain lubricating grease in while stopping the penetration of dirt and other contaminants to the pin/bush-ing bearing location.
Seal Guard Roller Chains
Specifi ed on larger pitch roller chains Seal Guard chains make use of a stainless steel seal to maintain lubricating grease in though stopping the penetration of filth together with other contaminants to the pin/bushing bearing region.
