Sintered Bushing Roller Chain (UR/ URN)

Servicing absolutely free chains employing sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain appropriate to a area wherever lubrication is tough. It makes use of bushings made of a sintered alloy which impregnates lubricating oil.
For the use that needs clean look, rustless form (URN) is available.
Suggested utilizes
?Situations in which lubrication is difficult or elongation of chain often takes place Remarks for use.
?Don’t use this chain in dusty environments. In such environments, use O-ring chains.
?This chain is for your use under light or medium load.Use O-ring chain whenever a significant affect is utilized to a chain.
?Set the chain feeding speed at 150m/min. or reduced.
Collection of chains
As for sintered bushing roller chains, the inner plates are thicker plus the pins are longer than these of common roller chains so as to compensate for that power lowered through the utilization of sintered bushings.
For choosing 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 velocity ranges.
For sintered bushing roller chains, “Low-speed selection” can’t be applied because the “Maximum allowable load” in the dimension table considers only the chain tensile tension and neglects the bushing power.
Connecting links and offset back links
For sintered bushing roller chain, R connecting hyperlinks are used for DID60 or smaller, and C connecting hyperlinks for DID80 or more substantial.
OJ might be made use of as offset backlinks. Please spot an order the connecting back links and offset back links specifying the style for sintered bushing roller chain.
Within the tables of maximum kilowatt ratings, the power of the connecting hyperlinks and offset hyperlinks are taken into account.
Rodas dentadas
Normal sprockets is often used for sintered bushing roller chains.
