Sintered Bushing Roller Chain (UR/ URN)

Upkeep cost-free chains working with sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain appropriate to a place in which lubrication is complicated. It uses bushings created of a sintered alloy which impregnates lubricating oil.
For your use that necessitates clean appearance, rustless type (URN) is available.
Recommended employs
?Conditions wherever lubrication is challenging or elongation of chain usually takes place Remarks for use.
?Will not use this chain in dusty environments. In such environments, use O-ring chains.
?This chain is for the use underneath light or medium load.Use O-ring chain when a substantial effect is applied to a chain.
?Set the chain feeding velocity at 150m/min. or decrease.
Choice of chains
As for sintered bushing roller chains, the inner plates are thicker as well as pins are longer than people of regular roller chains in order to compensate for that strength lowered through the utilization of sintered bushings.
For selecting an appropriate 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” are not able to be made use of since the “Maximum allowable load” during the dimension table considers only the chain tensile tension and neglects the bushing power.
Connecting hyperlinks and offset hyperlinks
For sintered bushing roller chain, R connecting backlinks are used for DID60 or smaller sized, and C connecting hyperlinks for DID80 or bigger.
OJ might be made use of as offset links. Please spot an purchase the connecting backlinks and offset links specifying the style for sintered bushing roller chain.
Inside the tables of highest kilowatt ratings, the strength on the connecting backlinks and offset back links are taken into consideration.
Sprockets
Regular sprockets could be employed for sintered bushing roller chains.
