We offer one of many most substantial lines of specialty Servicing Free of charge roller chain merchandise readily available to fi t a broad array of distinctive application requirements. Designers can select the series that finest fi ts the unique requires in the application. These chains should be specifi ed only when situations prohibit using lubricating oil considering that, on the whole, a very well lubricated standard chain will off er longer daily life in contrast using a upkeep free of charge chain. In some applications even so lubrication isn?¡¥t feasible and so the use of a self lubricated or sealed roller chain is necessary.
Standard Properties of Upkeep Free Roller Chain Goods
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil for the chain joint because of the friction created involving the pin and bushing because the chain articulates in excess of the sprocket teeth. These chains are rollerless and consequently use thick sectioned powdered metal bushings which might hold a higher volume of oil.
PT Form Roller Chains
Oil impregnated powdered metal sintered bushings release oil for the chain joint because of the friction designed concerning the pin and bushing because the chain articulates above the sprocket teeth. These chains possess rollers to smooth the action more than sprocket teeth. Roller link plates are a single dimension thicker to increase strength. Side plates and pins have special coatings to stop rust.
C-Type Roller Chains
Exact same as above except the side plates are all common thickness. The power in the CS Form chains is under the PT Type but higher than the SL type. Attachments with standard dimen-sions can be used for this series and hence they can be often used on little material handling conveyors.
Specifi ed on smaller sized pitch roller chains O-Ring chains utilize a rubber seal to help keep lubricating grease in though preventing the penetration of dirt and other contaminants in to the pin/bush-ing bearing spot.
Seal Guard Roller Chains
Specifi ed on more substantial pitch roller chains Seal Guard chains employ a stainless steel seal to maintain lubricating grease in even though stopping the penetration of grime and other contaminants in to the pin/bushing bearing region.
