Maintenance totally free chains using sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain appropriate to a location wherever lubrication is tough. It makes use of bushings created of the sintered alloy which impregnates lubricating oil.
To the use that requires clean look, rustless form (URN) is accessible.
Encouraged uses
?Circumstances the place lubrication is hard or elongation of chain often takes place Remarks for use.
?Will not use this chain in dusty environments. In this kind of environments, use O-ring chains.
?This chain is to the use below light or medium load.Use O-ring chain whenever a massive influence is utilized to a chain.
?Set the chain feeding speed at 150m/min. or lower.
Choice of chains
As for sintered bushing roller chains, the inner plates are thicker as well as pins are longer than those of standard roller chains in order to compensate to the power lowered from the utilization of sintered bushings.
For selecting a suitable chain, refer to “Selection of Chains”. Utilize the tables of optimum kilowatt ratings for sintered bushing roller chains that cover minimal velocity ranges.
For sintered bushing roller chains, “Low-speed selection” can’t be employed because the “Maximum allowable load” while in the dimension table considers only the chain tensile tension and neglects the bushing power.
Connecting links and offset links
For sintered bushing roller chain, R connecting backlinks are applied for DID60 or smaller, and C connecting backlinks for DID80 or more substantial.
OJ might be 
made use of as offset hyperlinks. Please area an order the connecting backlinks and offset hyperlinks specifying the form for sintered bushing roller chain.
Inside the tables of greatest kilowatt ratings, the power with the connecting back links and offset back links are taken into account.
Sprockets
Normal sprockets might be applied for sintered bushing roller chains.
