We offer one of the most extensive lines of specialty Upkeep Cost-free roller chain merchandise accessible to fi t a broad array of particular application desires. Designers can select the series that greatest fi ts the unique requires with the application. These chains needs to be specifi ed only when circumstances prohibit the use of lubricating oil because, generally, a well lubricated conventional chain will off er longer life in contrast having a servicing totally free chain. In some applications nevertheless lubrication isn?¡¥t feasible and so the use of a self lubricated or sealed roller chain is critical.
General Properties of Servicing Free of charge Roller Chain Items
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint because of the friction produced in between the pin and bushing because the chain articulates above the sprocket teeth. These chains are rollerless and hence use thick sectioned powdered metal bushings which may hold a high volume of oil.
PT Style Roller Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint as a result of friction developed in between the pin and bushing since the chain articulates more than the sprocket teeth. These chains possess rollers to smooth the action over sprocket teeth. Roller link plates are a single size thicker to increase strength. Side plates and pins have specific coatings to stop rust.
C-Type Roller Chains
Similar as above except the side plates are all conventional thickness. The power of the CS Type chains is lower than the PT Style but better than the SL kind. Attachments with standard dimen-sions may be used for this series and thus they may be generally used on small materials dealing with conveyors.
Specifi ed on smaller sized pitch roller chains O-Ring chains use a rubber seal to help keep lubricating grease in when stopping the penetration of dirt along with other contaminants to the pin/bush-ing bearing region.
Seal Guard Roller Chains
Specifi ed on larger pitch roller chains Seal Guard chains use a stainless steel seal to help keep lubricating grease in even though stopping the penetration of filth as well as other contaminants into the pin/bushing bearing place.
