We offer one of several most comprehensive lines of specialty Maintenance Totally free roller chain items out there to fi t a wide array of distinctive application wants. Designers can opt for the series that very best fi ts the unique requires of your application. These chains ought to be specifi ed only when conditions prohibit the usage of lubricating oil since, generally, a nicely lubricated regular chain will off er longer lifestyle in contrast with a maintenance totally free chain. In some applications nonetheless lubrication isn?¡¥t probable and so using a self lubricated or sealed roller chain is critical.
Common Properties of Maintenance Totally free Roller Chain Items
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint because of the friction developed between the pin and bushing as the chain articulates in excess of the sprocket teeth. These chains are rollerless and thus use thick sectioned powdered metal bushings which could hold a substantial volume of oil.
PT Type Roller Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint as a result of friction formulated in between the pin and bushing since the chain articulates over the sprocket teeth. These chains possess rollers to smooth the action in excess of sprocket teeth. Roller hyperlink plates are one particular dimension thicker to boost strength. Side plates and pins have distinctive coatings to prevent rust.
C-Type Roller Chains
Same as over except that the side plates are all normal thickness. The strength of the CS Form chains is under the PT Sort but higher compared to the SL kind. Attachments with typical dimen-sions can be used for this series and consequently they are frequently used on small materials handling conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains use a rubber seal to help keep lubricating grease in even though stopping the penetration of grime together with other contaminants into the pin/bush-ing bearing area.
Seal Guard Roller Chains
Specifi ed on greater pitch roller chains Seal Guard chains use a stainless steel seal to maintain lubricating grease in whilst avoiding the penetration of grime together with other contaminants in to the pin/bushing bearing location.
