Sintered Bushing Roller Chain (UR/ URN)

Maintenance free of charge chains making use of sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain ideal to a area wherever lubrication is tricky. It uses bushings created of a sintered alloy which impregnates lubricating oil.
For the use that involves clean physical appearance, rustless type (URN) is obtainable.
Encouraged uses
?Circumstances the place lubrication is complicated or elongation of chain usually happens Remarks for use.
?Will not use this chain in dusty environments. In such environments, use O-ring chains.
?This chain is for your use underneath light or medium load.Use O-ring chain whenever a significant effect is utilized to a chain.
?Set the chain feeding speed at 150m/min. or reduced.
Variety of chains
As for sintered bushing roller chains, the inner plates are thicker plus the pins are longer than those of standard roller chains in order to compensate for that strength lowered by the use of sintered bushings.
For choosing an appropriate 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” are unable to be applied since the “Maximum allowable load” within the dimension table considers only the chain tensile stress and neglects the bushing strength.
Connecting hyperlinks and offset backlinks
For sintered bushing roller chain, R connecting hyperlinks are made use of for DID60 or smaller, and C connecting links for DID80 or larger.
OJ may be applied as offset back links. Please area an purchase the connecting back links and offset back links specifying the type for sintered bushing roller chain.
In the tables of maximum kilowatt ratings, the strength on the connecting back links and offset backlinks are taken into consideration.
Standard sprockets can be employed for sintered bushing roller chains.
