Sintered Bushing Roller Chain (UR/ URN)

Servicing no cost chains making use of sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain appropriate to a place where lubrication is hard. It makes use of bushings created of a sintered alloy which impregnates lubricating oil.
For the use that requires clean appearance, rustless type (URN) is obtainable.
Proposed uses
?Situations wherever lubrication is complicated or elongation of chain often occurs Remarks for use.
?Don’t use this chain in dusty environments. In this kind of environments, use O-ring chains.
?This chain is for your use underneath light or medium load.Use O-ring chain whenever a massive impact is utilized to a chain.
?Set the chain feeding speed at 150m/min. or lower.
Variety of chains
As for sintered bushing roller chains, the inner plates are thicker and also the pins are longer than these of standard roller chains in order to compensate for that power lowered from the utilization of sintered bushings.
For deciding on a suitable chain, refer to “Selection of Chains”. Utilize the tables of optimum kilowatt ratings for sintered bushing roller chains that cover lower speed ranges.
For sintered bushing roller chains, “Low-speed selection” can’t be used since the “Maximum allowable load” during the dimension table considers only the chain tensile tension and neglects the bushing strength.
Connecting backlinks and offset hyperlinks
For sintered bushing roller chain, R connecting backlinks are applied for DID60 or smaller sized, and C connecting back links for DID80 or larger.
OJ may be utilised as offset backlinks. Please area an order the connecting back links and offset hyperlinks specifying the form for sintered bushing roller chain.
Inside the tables of highest kilowatt ratings, the power of the connecting back links and offset hyperlinks are taken into consideration.
Sprockets
Normal sprockets may be employed for sintered bushing roller chains.
