We offer one of the most comprehensive lines of specialty Maintenance No cost roller chain items accessible to fi t a broad array of unique application requirements. Designers can opt for the series that very best fi ts the distinct wants with the application. These chains really should be specifi ed only when circumstances prohibit the usage of lubricating oil since, usually, a very well lubricated standard chain will off er longer lifestyle in contrast with a servicing free chain. In some applications nonetheless lubrication isn?¡¥t achievable and so using a self lubricated or sealed roller chain is important.
Basic Properties of Servicing Free Roller Chain Goods
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint because of the friction formulated concerning 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 may hold a large volume of oil.
PT Kind Roller Chains
Oil impregnated powdered metal sintered bushings release oil for the chain joint because of the friction designed involving the pin and bushing since the chain articulates above the sprocket teeth. These chains possess rollers to smooth the action over sprocket teeth. Roller hyperlink plates are 1 size thicker to improve power. Side plates and pins have special coatings to avoid rust.
C-Type Roller Chains
Very same as above except the side plates are all common thickness. The power in the CS Sort chains is under the PT Type but greater compared to the SL kind. Attachments with typical dimen-sions can be used for this series and as a result they are typically made use of on smaller material managing 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 grime together with other contaminants to the pin/bush-ing bearing area.
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 when preventing the penetration of dirt and various contaminants into the pin/bushing bearing location.
