Sintered Bushing Roller Chain (UR/ URN)

Upkeep free chains making use of sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain suitable to a spot wherever lubrication is challenging. It employs bushings made of the sintered alloy which impregnates lubricating oil.
For your use that requires clean look, rustless type (URN) is accessible.
Advised utilizes
?Situations wherever lubrication is tough or elongation of chain often happens Remarks for use.
?Never use this chain in dusty environments. In such environments, use O-ring chains.
?This chain is for that use below light or medium load.Use O-ring chain whenever a large influence is utilized to a chain.
?Set the chain feeding velocity at 150m/min. or reduced.
Selection 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 that strength lowered by the use of sintered bushings.
For selecting an appropriate chain, refer to “Selection of Chains”. Use the tables of maximum kilowatt ratings for sintered bushing roller chains that cover low speed ranges.
For sintered bushing roller chains, “Low-speed selection” can not be used because the “Maximum allowable load” while in the dimension table considers only the chain tensile tension and neglects the bushing strength.
Connecting hyperlinks and offset links
For sintered bushing roller chain, R connecting links are utilized for DID60 or smaller sized, and C connecting links for DID80 or larger.
OJ is usually made use of as offset hyperlinks. Please spot an buy the connecting hyperlinks and offset back links specifying the sort for sintered bushing roller chain.
During the tables of maximum kilowatt ratings, the strength from the connecting links and offset links are taken into consideration.
Regular sprockets is often employed for sintered bushing roller chains.
