Sintered Bushing Roller Chain (UR/ URN)

Upkeep cost-free chains using sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain appropriate to a area the place lubrication is difficult. It uses bushings produced of the sintered alloy which impregnates lubricating oil.
For your use that demands clean appearance, rustless sort (URN) is obtainable.
Proposed utilizes
?Circumstances exactly where lubrication is tricky 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 affect is applied to a chain.
?Set the chain feeding speed at 150m/min. or lower.
Selection of chains
As for sintered bushing roller chains, the inner plates are thicker plus the pins are longer than people of conventional 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 since the “Maximum allowable load” in the dimension table considers only the chain tensile tension and neglects the bushing strength.
Connecting hyperlinks and offset back links
For sintered bushing roller chain, R connecting links are applied for DID60 or smaller sized, and C connecting links for DID80 or bigger.
OJ might be utilized as offset backlinks. Please place an purchase the connecting back links and offset hyperlinks specifying the style for sintered bushing roller chain.
Within the tables of maximum kilowatt ratings, the strength of the connecting backlinks and offset links are taken into consideration.
Common sprockets could be applied for sintered bushing roller chains.
