Maintenance Absolutely free Roller Chain – General Data

Basic Information and facts
We offer one of several most in depth lines of specialty Upkeep Free of charge roller chain items offered to fi t a broad array of special application requirements. Designers can opt for the series that best fi ts the particular wants in the application. These chains needs to be specifi ed only when circumstances prohibit using lubricating oil since, usually, a properly lubricated regular chain will off er longer lifestyle in contrast having a upkeep cost-free chain. In some applications even so lubrication isn?¡¥t feasible and so the usage of a self lubricated or sealed roller chain is important.
Standard 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 may hold a higher volume of oil.
PT Form Roller Chains
Oil impregnated powdered metal sintered bushings release oil towards 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 in excess of sprocket teeth. Roller link plates are a single dimension thicker to improve power. Side plates and pins have particular coatings to prevent rust.
C-Type Roller Chains
Similar as over except the side plates are all common thickness. The strength from the CS Style chains is lower than the PT Sort but higher than 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 material 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 avoiding 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 dirt as well as other contaminants to the pin/bushing bearing area.
