Basic Info
We offer among the most considerable lines of specialty Upkeep Totally free roller chain products accessible to fi t a wide array of special application needs. Designers can pick out the series that ideal fi ts the particular demands of your application. These chains should be specifi ed only when conditions prohibit the use of lubricating oil due to the fact, usually, a nicely lubricated regular chain will off er longer life compared using a maintenance absolutely free chain. In some applications however lubrication isn?¡¥t attainable and so using a self lubricated or sealed roller chain is critical.
Standard Properties of Servicing Totally free Roller Chain Merchandise
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint as a result of friction developed concerning the pin and bushing because the chain articulates in excess of the sprocket teeth. These chains are rollerless and therefore use thick sectioned powdered metal bushings which might hold a substantial volume of oil.
PT Form Roller Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint due to the friction produced among the pin and bushing because the chain articulates more than the sprocket teeth. These chains possess rollers to smooth the action over sprocket teeth. Roller link plates are one dimension thicker to increase strength. Side plates and pins have unique coatings to stop rust.
C-Type Roller Chains
Identical as above except the side plates are all standard thickness. The power on the CS Kind chains is less than the PT Form but greater than the SL variety. Attachments with typical dimen-sions can be used for this series and hence they’re normally employed on compact materials dealing with conveyors.
P-Ring Chains
Specifi ed on smaller pitch roller chains O-Ring chains make use of a rubber seal to keep lubricating grease in whilst avoiding the penetration of dirt along with other contaminants into the pin/bush-ing bearing spot.
Seal Guard Roller Chains
Specifi ed on greater pitch roller chains Seal Guard chains utilize a stainless steel seal to help keep lubricating grease in though avoiding the penetration of filth and various contaminants into the pin/bushing bearing location.
