We offer one of several most in depth lines of specialty Upkeep Cost-free roller chain merchandise offered to fi t a wide array of specific application needs. Designers can pick out the series that finest fi ts the distinct requires with the application. These chains must be specifi ed only when conditions prohibit the use of lubricating oil due to the fact, on the whole, a effectively lubricated regular chain will off er longer existence compared using a servicing totally free chain. In some applications even so lubrication isn?¡¥t achievable and so the usage of a self lubricated or sealed roller chain is important.
Basic Properties of Servicing Cost-free Roller Chain Solutions
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil to your chain joint due to the friction designed in between the pin and bushing as the chain articulates over the sprocket teeth. These chains are rollerless and hence use thick sectioned powdered metal bushings which might hold a substantial volume of oil.
PT Kind Roller Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint because of the friction designed amongst the pin and bushing as the chain articulates more than the sprocket teeth. These chains possess rollers to smooth the action above sprocket teeth. Roller link plates are 1 size thicker to increase power. Side plates and pins have distinctive coatings to avoid rust.
C-Type Roller Chains
Similar as above except the side plates are all common thickness. The power in the CS Variety chains is lower than the PT Style but better than the SL style. Attachments with regular dimen-sions can be utilized for this series and hence they’re generally made use of on little materials managing conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains make use of a rubber seal to maintain lubricating grease in while avoiding the penetration of grime and other contaminants in to the pin/bush-ing bearing location.
Seal Guard Roller Chains
Specifi ed on more substantial pitch roller chains Seal Guard chains use a stainless steel seal to maintain lubricating grease in when avoiding the penetration of dirt together with other contaminants to the pin/bushing bearing place.
