Standard Information and facts
We offer among the list of most in depth lines of specialty Upkeep Cost-free roller chain items offered to fi t a wide array of special application requirements. Designers can pick out the series that best fi ts the particular wants in the application. These chains must be specifi ed only when situations prohibit using lubricating oil since, in general, a properly lubricated normal chain will off er longer lifestyle in contrast using a upkeep absolutely free chain. In some applications even so lubrication isn?¡¥t feasible and so the usage of a self lubricated or sealed roller chain is necessary.
General Properties of Upkeep Absolutely free Roller Chain Solutions
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil for the chain joint as a result of friction produced concerning the pin and bushing as the chain articulates in excess of the sprocket teeth. These chains are rollerless and therefore 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 as a result of friction produced involving the pin and bushing since the chain articulates in excess of the sprocket teeth. These chains possess rollers to smooth the action over sprocket teeth. Roller hyperlink plates are a single dimension thicker to improve power. Side plates and pins have particular coatings to stop rust.
C-Type Roller Chains
Similar as over except the side plates are all typical thickness. The strength from the CS Type chains is lower than the PT Variety but higher compared to the SL variety. Attachments with regular dimen-sions can be utilized for this series and as a result they are really usually employed on smaller materials dealing with conveyors.
P-Ring Chains
Specifi ed on smaller pitch roller chains O-Ring chains employ a rubber seal to help keep lubricating grease in while preventing the penetration of grime along with other contaminants to the pin/bush-ing bearing spot.
Seal Guard Roller Chains
Specifi ed on bigger pitch roller chains Seal Guard chains use a stainless steel seal to maintain lubricating grease in even though stopping the penetration of grime along with other contaminants to the pin/bushing bearing area.
