Sintered Bushing Roller Chain (UR/ URN)

Maintenance absolutely free chains employing sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain suitable to a spot in which lubrication is difficult. It makes use of bushings made of the sintered alloy which impregnates lubricating oil.
For that use that demands clean visual appeal, rustless type (URN) is obtainable.
Suggested uses
?Situations where lubrication is hard or elongation of chain often occurs Remarks for use.
?Never use this chain in dusty environments. In this kind of environments, use O-ring chains.
?This chain is for the use beneath light or medium load.Use O-ring chain when a massive affect is utilized to a chain.
?Set the chain feeding pace at 150m/min. or reduce.
Selection of chains
As for sintered bushing roller chains, the inner plates are thicker as well as the pins are longer than individuals of typical roller chains so as to compensate for the strength lowered by the use of sintered bushings.
For choosing an appropriate chain, refer to “Selection of Chains”. Utilize the tables of maximum kilowatt ratings for sintered bushing roller chains that cover lower velocity ranges.
For sintered bushing roller chains, “Low-speed selection” are unable to be utilized since the “Maximum allowable load” inside the dimension table considers only the chain tensile tension and neglects the bushing power.
Connecting back links and offset back links
For sintered bushing roller chain, R connecting backlinks are utilized for DID60 or smaller, and C connecting backlinks for DID80 or larger.
OJ may be utilised as offset hyperlinks. Please place an purchase the connecting back links and offset back links specifying the sort for sintered bushing roller chain.
While in the tables of greatest kilowatt ratings, the strength with the connecting hyperlinks and offset back links are taken into account.
Sprockets
Common sprockets can be employed for sintered bushing roller chains.
