We offer one of the most in depth lines of specialty Maintenance Totally free roller chain goods offered to fi t a wide array of special application requirements. Designers can pick the series that greatest fi ts the individual requirements on the application. These chains need to be specifi ed only when situations prohibit the use of lubricating oil since, on the whole, a very well lubricated conventional chain will off er longer daily life in contrast by using a upkeep cost-free chain. In some applications nevertheless lubrication isn?¡¥t achievable and so the usage of a self lubricated or sealed roller chain is important.
Standard Properties of Servicing Absolutely 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 developed involving the pin and bushing since the chain articulates over the sprocket teeth. These chains are rollerless and consequently use thick sectioned powdered metal bushings which could hold a high volume of oil.
PT Kind Roller Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint as a result of friction designed among the pin and bushing since the chain articulates more than the sprocket teeth. These chains possess rollers to smooth the action more than sprocket teeth. Roller website link plates are a single dimension thicker to boost power. Side plates and pins have special coatings to stop rust.
C-Type Roller Chains
Similar as over except that the side plates are all standard thickness. The strength of your CS Sort chains is less than the PT Type but higher compared to the SL style. Attachments with normal dimen-sions can be used for this series and hence these are generally utilized on little materials handling conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains use a rubber seal to help keep lubricating grease in though preventing the penetration of dirt and other contaminants into the pin/bush-ing bearing spot.
Seal Guard Roller Chains
Specifi ed on more substantial pitch roller chains Seal Guard chains employ a stainless steel seal to help keep lubricating grease in when avoiding the penetration of dirt and other contaminants into the pin/bushing bearing area.
