We offer one of several most in depth lines of specialty Upkeep No cost roller chain solutions obtainable to fi t a broad array of distinctive application wants. Designers can opt for the series that greatest fi ts the individual requirements with the application. These chains ought to be specifi ed only when situations prohibit the use of lubricating oil considering that, generally, a properly lubricated normal chain will off er longer existence in contrast that has a servicing totally free chain. In some applications even so lubrication isn?¡¥t doable and so using a self lubricated or sealed roller chain is important.
Common Properties of Maintenance Absolutely free Roller Chain Solutions
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil for the chain joint because of the friction formulated between the pin and bushing since the chain articulates above the sprocket teeth. These chains are rollerless and hence use thick sectioned powdered metal bushings which may hold a higher volume of oil.
PT Variety Roller Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint because of the friction produced involving the pin and bushing as the chain articulates more than the sprocket teeth. These chains possess rollers to smooth the action above sprocket teeth. Roller hyperlink plates are 1 size thicker to improve strength. Side plates and pins have distinctive coatings to avoid rust.
C-Type Roller Chains
Identical as above except the side plates are all common thickness. The strength on the CS Form chains is lower than the PT Sort but greater than the SL form. Attachments with conventional dimen-sions can be used for this series and consequently they are generally used on modest materials dealing with conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains make use of a rubber seal to maintain lubricating grease in even though preventing the penetration of filth and various contaminants into the pin/bush-ing bearing area.
Seal Guard Roller Chains
Specifi ed on larger pitch roller chains Seal Guard chains use a stainless steel seal to help keep lubricating grease in though preventing the penetration of dirt and also other contaminants into the pin/bushing bearing place.
