Sintered Bushing Roller Chain (UR/ URN)

Maintenance free chains using sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain suitable to a place wherever lubrication is tricky. It employs bushings produced of a sintered alloy which impregnates lubricating oil.
To the use that requires clean appearance, rustless type (URN) is available.
Advised uses
?Situations exactly where lubrication is tough or elongation of chain frequently happens Remarks for use.
?Don’t use this chain in dusty environments. In such environments, use O-ring chains.
?This chain is for your use beneath light or medium load.Use O-ring chain when a big affect is utilized to a chain.
?Set the chain feeding speed at 150m/min. or reduced.
Variety of chains
As for sintered bushing roller chains, the inner plates are thicker and the pins are longer than people of standard roller chains so as to compensate for that strength lowered by the use of sintered bushings.
For selecting a suitable chain, refer to “Selection of Chains”. Use the tables of greatest kilowatt ratings for sintered bushing roller chains that cover low pace ranges.
For sintered bushing roller chains, “Low-speed selection” are not able to be applied because the “Maximum allowable load” during the dimension table considers only the chain tensile tension and neglects the bushing power.
Connecting backlinks and offset back links
For sintered bushing roller chain, R connecting links are made use of for DID60 or smaller sized, and C connecting back links for DID80 or larger.
OJ might be made use of as offset back links. Please spot an order the connecting hyperlinks and offset hyperlinks specifying the sort for sintered bushing roller chain.
While in the tables of maximum kilowatt ratings, the strength from the connecting back links and offset links are taken into account.
Normal sprockets could be employed for sintered bushing roller chains.
