Sintered Bushing Roller Chain (UR/ URN)

Servicing no cost chains employing sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain ideal to a area where lubrication is tough. It uses bushings made of the sintered alloy which impregnates lubricating oil.
For that use that involves clean look, rustless type (URN) is available.
Advised uses
?Circumstances exactly where lubrication is hard or elongation of chain commonly 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 beneath light or medium load.Use O-ring chain whenever a big affect is applied to a chain.
?Set the chain feeding velocity at 150m/min. or lower.
Collection of chains
As for sintered bushing roller chains, the inner plates are thicker and the pins are longer than those of standard roller chains in order to compensate for your power lowered by the utilization of sintered bushings.
For picking an appropriate chain, refer to “Selection of Chains”. Utilize the tables of maximum kilowatt ratings for sintered bushing roller chains that cover reduced velocity ranges.
For sintered bushing roller chains, “Low-speed selection” can not be applied since the “Maximum allowable load” in the dimension table considers only the chain tensile stress and neglects the bushing power.
Connecting hyperlinks and offset backlinks
For sintered bushing roller chain, R connecting back links are made use of for DID60 or smaller sized, and C connecting hyperlinks for DID80 or greater.
OJ might be employed as offset backlinks. Please place an order the connecting hyperlinks and offset back links specifying the type for sintered bushing roller chain.
In the tables of optimum kilowatt ratings, the strength on the connecting hyperlinks and offset back links are taken into account.
Sprockets
Standard sprockets is often employed for sintered bushing roller chains.
