Maintenance Free Roller Chain – Common Facts

General Details
We offer one of several most comprehensive lines of specialty Upkeep No cost roller chain products available to fi t a broad array of particular application wants. Designers can opt for the series that greatest fi ts the certain desires of your application. These chains ought to be specifi ed only when situations prohibit the usage of lubricating oil since, normally, a well lubricated standard chain will off er longer existence compared by using a maintenance totally free chain. In some applications on the other hand lubrication isn?¡¥t achievable and so the usage of a self lubricated or sealed roller chain is critical.
Standard Properties of Servicing Free Roller Chain Items
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint as a result of friction formulated between the pin and bushing because the chain articulates above the sprocket teeth. These chains are rollerless and thus use thick sectioned powdered metal bushings which could hold a high volume of oil.
PT Sort Roller Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint as a result of friction formulated amongst the pin and bushing since the chain articulates over the sprocket teeth. These chains possess rollers to smooth the action more than sprocket teeth. Roller link plates are a single dimension thicker to improve power. Side plates and pins have distinctive coatings to stop rust.
C-Type Roller Chains
Identical as over except that the side plates are all normal thickness. The strength with the CS Form chains is under the PT Form but greater than the SL sort. Attachments with standard dimen-sions may be used for this series and consequently they are generally applied on small materials dealing with conveyors.
P-Ring Chains
Specifi ed on smaller sized pitch roller chains O-Ring chains make use of a rubber seal to help keep lubricating grease in though preventing the penetration of dirt and various contaminants into the pin/bush-ing bearing place.
Seal Guard Roller Chains
Specifi ed on bigger pitch roller chains Seal Guard chains use a stainless steel seal to keep lubricating grease in even though avoiding the penetration of filth and other contaminants to the pin/bushing bearing region.
