We offer one of several most considerable lines of specialty Servicing Free roller chain goods accessible to fi t a wide array of specific application requires. Designers can opt for the series that greatest fi ts the particular needs on the application. These chains should be specifi ed only when circumstances prohibit the usage of lubricating oil considering that, in general, a nicely lubricated standard chain will off er longer daily life compared that has a servicing totally free chain. In some applications having said that lubrication isn?¡¥t feasible and so using a self lubricated or sealed roller chain is necessary.
Basic Properties of Maintenance Totally free Roller Chain Products
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil for the chain joint because of the friction formulated in between the pin and bushing since the chain articulates above 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 designed in between the pin and bushing as the chain articulates above the sprocket teeth. These chains possess rollers to smooth the action above sprocket teeth. Roller link plates are a single dimension thicker to improve power. Side plates and pins have particular coatings to stop rust.
C-Type Roller Chains
Identical as over except the side plates are all standard thickness. The strength in the CS Style chains is less than the PT Type but higher compared to the SL variety. Attachments with normal dimen-sions may be used for this series and therefore they are generally employed on tiny materials dealing with conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains employ a rubber seal to maintain lubricating grease in although stopping the penetration of dirt and other contaminants in to the pin/bush-ing bearing spot.
Seal Guard Roller Chains
Specifi ed on larger pitch roller chains Seal Guard chains use a stainless steel seal to maintain lubricating grease in even though preventing the penetration of grime and various contaminants in to the pin/bushing bearing location.
