焼結ブッシングローラーチェーン(UR / URN)

Servicing absolutely free chains utilizing sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain appropriate to a area where lubrication is challenging. It makes use of bushings produced of a sintered alloy which impregnates lubricating oil.
For that use that necessitates clean visual appeal, rustless style (URN) is obtainable.

?Circumstances wherever lubrication is tricky or elongation of chain frequently 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 for your use underneath light or medium load.Use O-ring chain when a huge impact is utilized to a chain.
?Set the chain feeding speed at 150m/min. or lower.

As for sintered bushing roller chains, the inner plates are thicker and the pins are longer than these of conventional roller chains so as to compensate to the power lowered by the use of sintered bushings.
For deciding on a suitable chain, refer to “Selection of Chains”. Make use of the tables of maximum kilowatt ratings for sintered bushing roller chains that cover lower speed ranges.
For sintered bushing roller chains, “Low-speed selection” can’t be used because the “Maximum allowable load” during the dimension table considers only the chain tensile tension and neglects the bushing strength.
