We offer on the list of most substantial lines of specialty Upkeep Cost-free roller chain products out there to fi t a broad array of unique application requires. Designers can pick out the series that very best fi ts the certain desires of the application. These chains really should be specifi ed only when situations prohibit the use of lubricating oil considering that, normally, a well lubricated common chain will off er longer daily life in contrast that has a maintenance absolutely free chain. In some applications however lubrication isn?¡¥t probable and so the use of a self lubricated or sealed roller chain is necessary.
Basic Properties of Maintenance Cost-free Roller Chain Goods
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint because of the friction formulated between the pin and bushing because the chain articulates more than the sprocket teeth. These chains are rollerless and hence use thick sectioned powdered metal bushings which could hold a substantial volume of oil.
PT Sort Roller Chains
Oil impregnated powdered metal sintered bushings release oil for the chain joint due to the friction produced amongst the pin and bushing since the chain articulates above the sprocket teeth. These chains possess rollers to smooth the action over sprocket teeth. Roller link plates are 1 size thicker to boost power. Side plates and pins have distinctive coatings to prevent rust.
C-Type Roller Chains
Very same as over except the side plates are all regular thickness. The strength in the CS Kind chains is under the PT Style but better compared to the SL type. Attachments with regular dimen-sions can be utilized for this series and thus they’re typically employed on small material managing conveyors.
Specifi ed on smaller sized pitch roller chains O-Ring chains make use of a rubber seal to help keep lubricating grease in when stopping the penetration of filth as well as other contaminants to the pin/bush-ing bearing area.
Seal Guard Roller Chains
Specifi ed on greater pitch roller chains Seal Guard chains utilize a stainless steel seal to help keep lubricating grease in whilst stopping the penetration of dirt together with other contaminants in to the pin/bushing bearing location.
