We offer one of many most substantial lines of specialty Upkeep Free roller chain merchandise accessible to fi t a broad array of unique application wants. Designers can opt for the series that most effective fi ts the unique requirements from the application. These chains ought to be specifi ed only when circumstances prohibit the use of lubricating oil considering the fact that, usually, a very well lubricated common chain will off er longer life in contrast with a maintenance totally free chain. In some applications however lubrication isn?¡¥t attainable and so the use of a self lubricated or sealed roller chain is important.
Common Properties of Maintenance Free Roller Chain Items
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint due to the friction created amongst the pin and bushing as the chain articulates more than the sprocket teeth. These chains are rollerless and thus use thick sectioned powdered metal bushings which might hold a higher volume of oil.
PT Form 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 since the chain articulates over the sprocket teeth. These chains possess rollers to smooth the action more than sprocket teeth. Roller link plates are one size thicker to boost strength. Side plates and pins have distinctive coatings to prevent rust.
C-Type Roller Chains
Very same as over except the side plates are all conventional thickness. The strength in the CS Form chains is under the PT Style but greater than the SL variety. Attachments with conventional dimen-sions can be used for this series and as a result they are normally applied on little materials dealing with conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains use a rubber seal to keep lubricating grease in while preventing the penetration of filth and other contaminants into the pin/bush-ing bearing location.
Seal Guard Roller Chains
Specifi ed on bigger pitch roller chains Seal Guard chains use a stainless steel seal to help keep lubricating grease in though preventing the penetration of dirt together with other contaminants in to the pin/bushing bearing location.
