Sintered Bushing Roller Chain (UR/ URN)

Maintenance totally free chains applying sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain appropriate to a place where lubrication is tough. It utilizes bushings made of a sintered alloy which impregnates lubricating oil.
For that use that calls for clean appearance, rustless variety (URN) is obtainable.
Recommended makes use of
?Circumstances wherever lubrication is complicated or elongation of chain often occurs Remarks for use.
?Don’t use this chain in dusty environments. In this kind of environments, use O-ring chains.
?This chain is for your use below light or medium load.Use O-ring chain whenever a large effect is utilized to a chain.
?Set the chain feeding pace at 150m/min. or decrease.
Variety of chains
As for sintered bushing roller chains, the inner plates are thicker and also the pins are longer than individuals of common roller chains so as to compensate for the power lowered from the utilization of sintered bushings.
For selecting an appropriate chain, refer to “Selection of Chains”. Utilize the tables of greatest kilowatt ratings for sintered bushing roller chains that cover lower speed ranges.
For sintered bushing roller chains, “Low-speed selection” can’t be employed since the “Maximum allowable load” inside the dimension table considers only the chain tensile tension and neglects the bushing strength.
Connecting links and offset back links
For sintered bushing roller chain, R connecting links are used for DID60 or smaller, and C connecting hyperlinks for DID80 or bigger.
OJ may be applied as offset links. Please area an purchase the connecting hyperlinks and offset hyperlinks specifying the form for sintered bushing roller chain.
Within the tables of optimum kilowatt ratings, the power with the connecting links and offset hyperlinks are taken into account.
Conventional sprockets could be made use of for sintered bushing roller chains.
