We offer one of the most substantial lines of specialty Maintenance Totally free roller chain merchandise offered to fi t a wide array of particular application desires. Designers can decide on the series that best fi ts the distinct requires of the application. These chains should be specifi ed only when circumstances prohibit the use of lubricating oil considering that, in general, a well lubricated regular chain will off er longer lifestyle compared which has a maintenance cost-free chain. In some applications having said that lubrication isn?¡¥t feasible and so the use of a self lubricated or sealed roller chain is important.
Basic Properties of Servicing Absolutely free Roller Chain Merchandise
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil to your chain joint because of the friction produced amongst the pin and bushing as the chain articulates more than the sprocket teeth. These chains are rollerless and hence use thick sectioned powdered metal bushings which might hold a substantial volume of oil.
PT Form Roller Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint due to the friction produced in between the pin and bushing since the chain articulates above the sprocket teeth. These chains possess rollers to smooth the action above sprocket teeth. Roller link plates are a single dimension thicker to improve strength. Side plates and pins have specific coatings to avoid rust.
C-Type Roller Chains
Identical as above except the side plates are all regular thickness. The strength with the CS Sort chains is under the PT Variety but higher than the SL variety. Attachments with typical dimen-sions may be used for this series and thus they are really usually made use of on little material handling conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains use a rubber seal to maintain lubricating grease in although preventing the penetration of dirt together with other contaminants in to the pin/bush-ing bearing area.
Seal Guard Roller Chains
Specifi ed on larger pitch roller chains Seal Guard chains employ a stainless steel seal to keep lubricating grease in although stopping the penetration of dirt and various contaminants into the pin/bushing bearing area.
