Sintered Bushing Roller Chain (UR/ URN)

Upkeep absolutely free chains utilizing sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain ideal to a area wherever lubrication is tough. It uses bushings created of the sintered alloy which impregnates lubricating oil.
For your use that demands clean appearance, rustless sort (URN) is obtainable.
Recommended utilizes
?Circumstances in which lubrication is complicated or elongation of chain usually occurs Remarks for use.
?Do not 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 huge impact is applied 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 plus the pins are longer than people of standard roller chains so as to compensate for that power lowered by the use of sintered bushings.
For choosing a suitable chain, refer to “Selection of Chains”. Make use of the tables of greatest kilowatt ratings for sintered bushing roller chains that cover lower pace ranges.
For sintered bushing roller chains, “Low-speed selection” cannot be used because the “Maximum allowable load” in the dimension table considers only the chain tensile tension and neglects the bushing strength.
Connecting hyperlinks and offset links
For sintered bushing roller chain, R connecting hyperlinks are applied for DID60 or smaller sized, and C connecting hyperlinks for DID80 or bigger.
OJ is often utilized as offset backlinks. Please place an buy the connecting links and offset backlinks specifying the type for sintered bushing roller chain.
Within the tables of maximum kilowatt ratings, the strength of the connecting backlinks and offset hyperlinks are taken into consideration.
Common sprockets might be applied for sintered bushing roller chains.
