Sintered Bushing Roller Chain (UR/ URN)

Maintenance absolutely free chains working with sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain appropriate to a spot wherever lubrication is difficult. It employs bushings produced of a sintered alloy which impregnates lubricating oil.
For your use that needs clean look, rustless type (URN) is available.
Advised makes use of
?Circumstances exactly where lubrication is hard or elongation of chain often happens 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 huge influence 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 plus the pins are longer than these of normal roller chains in order to compensate for the power lowered through the use of sintered bushings.
For deciding on a suitable chain, refer to “Selection of Chains”. Make use of the tables of maximum kilowatt ratings for sintered bushing roller chains that cover minimal velocity ranges.
For sintered bushing roller chains, “Low-speed selection” can not be employed since the “Maximum allowable load” while in the dimension table considers only the chain tensile stress and neglects the bushing strength.
Connecting backlinks and offset back links
For sintered bushing roller chain, R connecting links are made use of for DID60 or smaller, and C connecting hyperlinks for DID80 or greater.
OJ is usually made use of as offset links. Please spot an order the connecting back links and offset links specifying the form for sintered bushing roller chain.
During the tables of maximum kilowatt ratings, the strength of the connecting back links and offset backlinks are taken under consideration.
Common sprockets is often employed for sintered bushing roller chains.
