We offer one of several most extensive lines of specialty Maintenance Free roller chain goods obtainable to fi t a broad array of special application needs. Designers can select the series that greatest fi ts the certain requires from the application. These chains must be specifi ed only when conditions prohibit the usage of lubricating oil because, in general, a properly lubricated conventional chain will off er longer daily life in contrast which has a upkeep free of charge chain. In some applications even so lubrication isn?¡¥t feasible and so the usage of a self lubricated or sealed roller chain is critical.
Standard Properties of Servicing No cost Roller Chain Merchandise
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint because of the friction created between the pin and bushing since the chain articulates above the sprocket teeth. These chains are rollerless and thus use thick sectioned powdered metal bushings which might hold a substantial volume of oil.
PT Type Roller Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint because of the friction formulated amongst the pin and bushing because the chain articulates in excess of the sprocket teeth. These chains possess rollers to smooth the action more than sprocket teeth. Roller link plates are one particular dimension thicker to improve power. Side plates and pins have specific coatings to prevent rust.
C-Type Roller Chains
Very same as over except the side plates are all standard thickness. The strength in the CS Style chains is lower than the PT Kind but greater than the SL form. Attachments with conventional dimen-sions can be utilized for this series and thus they may be generally applied on little material managing conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains make use of a rubber seal to help keep lubricating grease in although avoiding the penetration of dirt and other contaminants into the pin/bush-ing bearing region.
Seal Guard Roller Chains
Specifi ed on greater pitch roller chains Seal Guard chains employ a stainless steel seal to maintain lubricating grease in even though avoiding the penetration of filth and other contaminants into the pin/bushing bearing area.
