We offer one of several most in depth lines of specialty Servicing Free roller chain items out there to fi t a wide array of unique application requirements. Designers can pick out the series that very best fi ts the distinct desires from the application. These chains needs to be specifi ed only when situations prohibit the use of lubricating oil considering that, in general, a effectively lubricated conventional chain will off er longer lifestyle in contrast with a maintenance free of charge chain. In some applications however lubrication isn?¡¥t achievable and so the use of a self lubricated or sealed roller chain is critical.
Basic Properties of Upkeep Cost-free Roller Chain Solutions
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint because of the friction produced amongst the pin and bushing as the chain articulates in excess of the sprocket teeth. These chains are rollerless and as a result use thick sectioned powdered metal bushings which might 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 in between the pin and bushing as the chain articulates over the sprocket teeth. These chains possess rollers to smooth the action over sprocket teeth. Roller link plates are one particular size thicker to increase power. Side plates and pins have special coatings to prevent rust.
C-Type Roller Chains
Exact same as above except that the side plates are all standard thickness. The power of the CS Form chains is lower than the PT Kind but greater than the SL kind. Attachments with standard dimen-sions can be utilized for this series and as a result they’re frequently made use of on compact materials managing conveyors.
Specifi ed on smaller sized pitch roller chains O-Ring chains make use of a rubber seal to maintain lubricating grease in although avoiding the penetration of dirt along with other contaminants into the pin/bush-ing bearing area.
Seal Guard Roller Chains
Specifi ed on larger pitch roller chains Seal Guard chains make use of a stainless steel seal to help keep lubricating grease in when stopping the penetration of filth together with other contaminants to the pin/bushing bearing place.
