Basic Information
We offer among the most substantial lines of specialty Maintenance Absolutely free roller chain solutions out there to fi t a broad array of special application wants. Designers can decide on the series that finest fi ts the specific demands on the application. These chains need to be specifi ed only when conditions prohibit using lubricating oil due to the fact, generally, a effectively lubricated normal chain will off er longer life in contrast which has a maintenance absolutely free chain. In some applications having said that lubrication isn?¡¥t possible and so the use of a self lubricated or sealed roller chain is important.
General Properties of Upkeep Free of charge Roller Chain Products
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint because of 
the friction formulated among the pin and bushing since the chain articulates more than the sprocket teeth. These chains are rollerless and consequently use thick sectioned powdered metal bushings which may hold a substantial volume of oil.
PT Style Roller Chains
Oil impregnated powdered metal sintered bushings release oil to your chain joint due to the friction formulated in between the pin and bushing as the chain articulates over the sprocket teeth. These chains possess rollers to smooth the action more than sprocket teeth. Roller link plates are 1 dimension thicker to increase strength. Side plates and pins have unique coatings to stop rust.
C-Type Roller Chains
Similar as over except that the side plates are all normal thickness. The strength of the CS Variety chains is under the PT Sort but greater compared to the SL type. Attachments with conventional dimen-sions can be used for this series and consequently they are really often employed on compact materials handling conveyors.
P-Ring Chains
Specifi ed on smaller sized pitch roller chains O-Ring chains utilize a rubber seal to maintain lubricating grease in although avoiding the penetration of grime along with other contaminants into the pin/bush-ing bearing place.
Seal Guard Roller Chains
Specifi ed on bigger pitch roller chains Seal Guard chains utilize a stainless steel seal to maintain lubricating grease in whilst stopping the penetration of dirt and other contaminants to the pin/bushing bearing place.
