Sintered Bushing Roller Chain (UR/ URN)

Upkeep free of charge chains making use of sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain ideal to a spot where lubrication is hard. It employs bushings made of a sintered alloy which impregnates lubricating oil.
For the use that demands clean physical appearance, rustless style (URN) is available.
Suggested utilizes
?Circumstances wherever lubrication is difficult or elongation of chain regularly takes place Remarks for use.
?Do not 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 substantial effect is utilized to a chain.
?Set the chain feeding pace at 150m/min. or reduce.
Collection of chains
As for sintered bushing roller chains, the inner plates are thicker and the pins are longer than these of normal roller chains so as to compensate to the power lowered from the use of sintered bushings.
For picking a suitable chain, refer to “Selection of Chains”. Utilize the tables of highest kilowatt ratings for sintered bushing roller chains that cover lower speed ranges.
For sintered bushing roller chains, “Low-speed selection” can not be applied because the “Maximum allowable load” in the dimension table considers only the chain tensile stress and neglects the bushing power.
Connecting backlinks and offset hyperlinks
For sintered bushing roller chain, R connecting back links are utilized for DID60 or smaller, and C connecting back links for DID80 or bigger.
OJ is often employed as offset backlinks. Please place an purchase the connecting back links and offset backlinks specifying the type for sintered bushing roller chain.
During the tables of optimum kilowatt ratings, the power from the connecting links and offset links are taken into account.
Common sprockets is usually utilized for sintered bushing roller chains.
