Sintered Bushing Roller Chain (UR/ URN)

Maintenance no cost chains making use of sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain ideal to a area exactly where lubrication is difficult. It utilizes bushings made of a sintered alloy which impregnates lubricating oil.
To the use that requires clean look, rustless kind (URN) is accessible.
Advisable employs
?Situations wherever lubrication is tricky or elongation of chain usually takes place Remarks for use.
?Don’t use this chain in dusty environments. In such environments, use O-ring chains.
?This chain is for that use beneath light or medium load.Use O-ring chain whenever a big impact is utilized to a chain.
?Set the chain feeding velocity at 150m/min. or reduce.
Variety of chains
As for sintered bushing roller chains, the inner plates are thicker as well as pins are longer than those of conventional roller chains in order to compensate to the power lowered from the utilization of sintered bushings.
For selecting a suitable chain, refer to “Selection of Chains”. Make use of the tables of maximum kilowatt ratings for sintered bushing roller chains that cover reduced speed ranges.
For sintered bushing roller chains, “Low-speed selection” can not be utilised because the “Maximum allowable load” while in the dimension table considers only the chain tensile tension and neglects the bushing strength.
Connecting links and offset back links
For sintered bushing roller chain, R connecting backlinks are utilised for DID60 or smaller sized, and C connecting hyperlinks for DID80 or greater.
OJ is usually applied as offset hyperlinks. Please spot an order the connecting links and offset backlinks specifying the style for sintered bushing roller chain.
In the tables of highest kilowatt ratings, the strength on the connecting links and offset hyperlinks are taken under consideration.
Sprockets
Normal sprockets is often utilised for sintered bushing roller chains.
