We offer among the list of most extensive lines of specialty Servicing Free roller chain items available to fi t a broad array of exclusive application demands. Designers can pick out the series that ideal fi ts the particular desires of your application. These chains should be specifi ed only when circumstances prohibit the use of lubricating oil considering that, usually, a very well lubricated standard chain will off er longer life in contrast by using a maintenance free chain. In some applications on the other hand lubrication isn?¡¥t probable and so the use of a self lubricated or sealed roller chain is critical.
General Properties of Servicing Absolutely free Roller Chain Merchandise
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint as a result of friction produced amongst the pin and bushing since the chain articulates over the sprocket teeth. These chains are rollerless and as a result 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 because of the friction developed amongst the pin and bushing as the chain articulates over the sprocket teeth. These chains possess rollers to smooth the action in excess of sprocket teeth. Roller hyperlink plates are one dimension thicker to improve power. Side plates and pins have special coatings to avoid rust.
C-Type Roller Chains
Similar as over except the side plates are all standard thickness. The strength in the CS Type chains is lower than the PT Type but higher compared to the SL type. Attachments with typical dimen-sions may be used for this series and as a result they are normally employed on small material dealing with conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains use a rubber seal to maintain lubricating grease in though preventing the penetration of dirt and also other contaminants to the pin/bush-ing bearing spot.
Seal Guard Roller Chains
Specifi ed on larger pitch roller chains Seal Guard chains make use of a stainless steel seal to keep lubricating grease in whilst stopping the penetration of filth and also other contaminants into the pin/bushing bearing area.
