We offer one of many most intensive lines of specialty Servicing No cost roller chain products obtainable to fi t a wide array of distinctive application requires. Designers can decide on the series that finest fi ts the particular requirements of the application. These chains really should be specifi ed only when situations prohibit the usage of lubricating oil considering that, on the whole, a nicely lubricated normal chain will off er longer existence in contrast using a upkeep absolutely free chain. In some applications even so lubrication isn?¡¥t attainable and so the usage of a self lubricated or sealed roller chain is important.
Common Properties of Maintenance Free Roller Chain Merchandise
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil for the chain joint as a result of friction designed amongst the pin and bushing since the chain articulates in excess of the sprocket teeth. These chains are rollerless and as a result use thick sectioned powdered metal bushings which might hold a higher volume of oil.
PT Sort Roller Chains
Oil impregnated powdered metal sintered bushings release oil to your chain joint due to the friction created concerning the pin and bushing as the chain articulates in excess of the sprocket teeth. These chains possess rollers to smooth the action more than sprocket teeth. Roller hyperlink plates are one particular dimension thicker to boost strength. Side plates and pins have distinctive coatings to avoid rust.
C-Type Roller Chains
Exact same as over except that the side plates are all regular thickness. The strength in the CS Form chains is under the PT Type but greater than the SL form. Attachments with normal dimen-sions can be used for this series and therefore they are really often employed on modest material managing conveyors.
Specifi ed on smaller sized pitch roller chains O-Ring chains employ a rubber seal to maintain lubricating grease in though avoiding the penetration of grime together with other contaminants into the pin/bush-ing bearing spot.
Seal Guard Roller Chains
Specifi ed on greater pitch roller chains Seal Guard chains employ a stainless steel seal to maintain lubricating grease in though avoiding the penetration of dirt together with other contaminants in to the pin/bushing bearing area.
