Sintered Bushing Roller Chain (UR/ URN)

Maintenance free of charge chains using sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain ideal to a place the place lubrication is tough. It employs bushings produced of a sintered alloy which impregnates lubricating oil.
For your use that demands clean physical appearance, rustless kind (URN) is obtainable.
Advisable utilizes
?Circumstances the place lubrication is challenging or elongation of chain often happens Remarks for use.
?Never 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 huge affect is applied to a chain.
?Set the chain feeding pace at 150m/min. or lower.
Choice of chains
As for sintered bushing roller chains, the inner plates are thicker and the pins are longer than those of common roller chains in order to compensate for your strength lowered from the utilization of sintered bushings.
For picking out a suitable chain, refer to “Selection of Chains”. Utilize the tables of greatest kilowatt ratings for sintered bushing roller chains that cover very low speed ranges.
For sintered bushing roller chains, “Low-speed selection” can’t be employed because the “Maximum allowable load” during 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 links are employed for DID60 or smaller sized, and C connecting links for DID80 or larger.
OJ is usually employed as offset backlinks. Please spot an purchase the connecting backlinks and offset hyperlinks specifying the kind for sintered bushing roller chain.
Inside the tables of maximum kilowatt ratings, the strength from the connecting backlinks and offset backlinks are taken under consideration.
Common sprockets can be utilized for sintered bushing roller chains.
