Sintered Bushing Roller Chain (UR/ URN)

Maintenance cost-free chains working with sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain ideal to a spot wherever lubrication is challenging. It employs bushings produced of the sintered alloy which impregnates lubricating oil.
For your use that demands clean appearance, rustless sort (URN) is accessible.
Proposed makes use of
?Conditions wherever lubrication is tricky or elongation of chain frequently happens Remarks for use.
?Do not use this chain in dusty environments. In this kind of environments, use O-ring chains.
?This chain is for that use underneath light or medium load.Use O-ring chain when a large effect is utilized to a chain.
?Set the chain feeding pace at 150m/min. or reduced.
Selection of chains
As for sintered bushing roller chains, the inner plates are thicker and also the pins are longer than those of common roller chains so as to compensate to the power lowered from the use of sintered bushings.
For selecting a suitable chain, refer to “Selection of Chains”. Utilize the tables of optimum kilowatt ratings for sintered bushing roller chains that cover low pace ranges.
For sintered bushing roller chains, “Low-speed selection” can not be utilised since the “Maximum allowable load” during the dimension table considers only the chain tensile tension and neglects the bushing strength.
Connecting backlinks and offset backlinks
For sintered bushing roller chain, R connecting hyperlinks are made use of for DID60 or smaller sized, and C connecting hyperlinks for DID80 or greater.
OJ is usually utilised as offset backlinks. Please location an order the connecting backlinks and offset links specifying the kind for sintered bushing roller chain.
While in the tables of maximum kilowatt ratings, the power from the connecting hyperlinks and offset back links are taken into consideration.
Common sprockets could be applied for sintered bushing roller chains.
