Basic Facts
We offer on the list of most considerable lines of specialty Servicing Totally free roller chain solutions obtainable to fi t a wide array of special application desires. Designers can select the series that best fi ts the unique needs from the application. These chains need to be specifi ed only when conditions prohibit using lubricating oil given that, usually, a effectively lubricated common chain will off er longer daily life in contrast which has a upkeep absolutely free chain. In some applications nevertheless lubrication isn?¡¥t probable and so using a self lubricated or sealed roller chain is important.
General Properties of Maintenance Cost-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 produced involving the pin and bushing since the chain articulates over the sprocket teeth. These chains are rollerless and hence use thick sectioned powdered metal bushings which may hold a large volume of oil.
PT Style Roller Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint due to the friction designed concerning 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 size thicker to increase strength. Side plates and pins have unique coatings to avoid rust.
C-Type Roller Chains
Similar as over except the side plates are all typical thickness. The power of the CS Kind chains is less than the PT Type but higher compared to the SL form. Attachments with normal dimen-sions can be used for this series and thus they can be often used on tiny materials handling conveyors.
P-Ring Chains
Specifi ed on smaller pitch 
roller chains O-Ring chains utilize a rubber seal to maintain lubricating grease in whilst avoiding the penetration of filth as well as other contaminants to the pin/bush-ing bearing region.
Seal Guard Roller Chains
Specifi ed on more substantial pitch roller chains Seal Guard chains utilize a stainless steel seal to help keep lubricating grease in while preventing the penetration of dirt along with other contaminants in to the pin/bushing bearing place.
