Maintenance Free Roller Chain – Basic Facts

Basic Info
We offer among the most extensive lines of specialty Maintenance Cost-free roller chain merchandise out there to fi t a wide array of distinctive application wants. Designers can pick out the series that very best fi ts the distinct requirements from the application. These chains should be specifi ed only when situations prohibit the usage of lubricating oil considering the fact that, normally, a properly lubricated conventional chain will off er longer daily life in contrast having a upkeep absolutely free chain.

Basic Properties of Servicing Cost-free Roller Chain Merchandise
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint due to the friction formulated amongst 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 might hold a higher volume of oil.
PT Type Roller Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint as a result of friction produced between the pin and bushing because the chain articulates above the sprocket teeth. These chains possess rollers to smooth the action above sprocket teeth. Roller hyperlink plates are one particular size thicker to increase power. Side plates and pins have specific coatings to stop rust.
C-Type Roller Chains
Similar as over except that the side plates are all typical thickness. The power on the CS Variety chains is less than the PT Type but higher than the SL kind. Attachments with common dimen-sions can be used for this series and as a result they’re frequently applied on modest materials dealing with conveyors.
P-Ring Chains
Specifi ed on smaller sized pitch roller chains O-Ring chains use a rubber seal to keep lubricating grease in even though preventing the penetration of dirt and other contaminants into the pin/bush-ing bearing region.
