Standard Information
We offer on the list of most intensive lines of specialty Maintenance Totally free roller chain solutions out there to fi t a broad array of exclusive application requirements. Designers can pick the series that ideal fi ts the particular demands of the application. These chains must be specifi ed only when conditions prohibit the use of lubricating oil considering the fact that, usually, a properly lubricated standard chain will off er longer life compared having a upkeep cost-free chain. In some applications nonetheless lubrication isn?¡¥t attainable and so using a self lubricated or sealed roller chain is important.
Common Properties of Upkeep Cost-free Roller Chain Products
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint due to the friction produced in between the pin and bushing as the chain articulates above the sprocket teeth. These chains are rollerless and so 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 to the chain joint due to the friction created concerning the pin and bushing since the chain articulates in excess of the sprocket teeth. These chains possess rollers to smooth the action above sprocket teeth. Roller link plates are one particular size thicker to increase strength. Side plates and pins have special coatings to stop rust.
C-Type Roller Chains
Same as over except that the side plates are all regular thickness. The strength in the CS Kind chains is less than the PT Sort but higher than the SL kind. Attachments with conventional dimen-sions may be used for this series and therefore these are normally utilized on compact material managing conveyors.
P-Ring Chains
Specifi ed on smaller sized pitch roller chains O-Ring chains make use of a rubber seal to keep lubricating grease in whilst preventing the penetration of grime along with other contaminants to the pin/bush-ing bearing region.
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 preventing the penetration of dirt together with other contaminants to the pin/bushing bearing place.
