We offer one of the most substantial lines of specialty Maintenance Totally free roller chain items readily available to fi t a wide array of specific application requirements. Designers can pick the series that most effective fi ts the unique wants in the application. These chains should be specifi ed only when situations prohibit the usage of lubricating oil due to the fact, normally, a well lubricated regular chain will off er longer lifestyle compared using a servicing no cost chain. In some applications however lubrication isn?¡¥t attainable and so using a self lubricated or sealed roller chain is important.
General Properties of Maintenance Totally free Roller Chain Products
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil on the chain joint as a result of friction designed among the pin and bushing as the chain articulates over the sprocket teeth. These chains are rollerless and as a result use thick sectioned powdered metal bushings which can hold a high volume of oil.
PT Sort Roller Chains
Oil impregnated powdered metal sintered bushings release oil towards the chain joint due to the friction created involving the pin and bushing since the chain articulates more than the sprocket teeth. These chains possess rollers to smooth the action above sprocket teeth. Roller website link plates are 1 dimension thicker to increase power. Side plates and pins have special coatings to stop rust.
C-Type Roller Chains
Same as above except that the side plates are all common thickness. The strength on the CS Kind chains is lower than the PT Variety but higher compared to the SL type. Attachments with normal dimen-sions can be utilized for this series and as a result these are frequently used on smaller materials dealing with conveyors.
Specifi ed on smaller pitch roller chains O-Ring chains employ a rubber seal to maintain lubricating grease in when stopping the penetration of dirt as well as other contaminants into the pin/bush-ing bearing region.
Seal Guard Roller Chains
Specifi ed on larger pitch roller chains Seal Guard chains utilize a stainless steel seal to help keep lubricating grease in when preventing the penetration of dirt along with other contaminants into the pin/bushing bearing region.
