Common Information and facts
We offer on the list of most considerable lines of specialty Maintenance Totally free roller chain items out there to fi t a broad array of special application requirements. Designers can select the series that finest fi ts the particular wants with the application. These chains ought to be specifi ed only when circumstances prohibit using lubricating oil given that, on the whole, a properly lubricated common chain will off er longer existence compared having a upkeep free chain. In some applications nevertheless lubrication isn?¡¥t feasible and so the usage of a self lubricated or sealed roller chain is critical.
Basic Properties of Upkeep Free Roller Chain Goods
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint as a result of friction produced amongst the pin and bushing since the chain articulates more than the sprocket teeth. These chains are rollerless and as a result 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 on the chain joint because of the friction created involving the pin and bushing as the chain articulates over the sprocket teeth. These chains possess rollers to smooth the action above sprocket teeth. Roller link plates are a single size thicker to boost power. Side plates and pins have particular coatings to avoid rust.
C-Type Roller Chains
Identical as over except the side plates are all regular thickness. The power from the CS Type chains is under the PT Kind but higher compared to the SL kind. Attachments with conventional dimen-sions can be used for this series and as a result they can be often used on smaller material handling conveyors.
P-Ring Chains
Specifi ed on smaller pitch roller chains O-Ring chains utilize a rubber seal to maintain lubricating grease in though avoiding the penetration of filth and other contaminants in to the pin/bush-ing bearing spot.
Seal Guard Roller Chains
Specifi ed on more substantial pitch roller chains Seal Guard chains make use of a stainless steel seal to help keep lubricating grease in even though avoiding the penetration of filth and other contaminants to the pin/bushing bearing region.
