Maintenance totally free chains using sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain suitable to a spot wherever lubrication is difficult. It uses bushings produced of the sintered alloy which impregnates lubricating oil.
To the use that demands clean appearance, rustless style (URN) is obtainable.
Advised makes use of
?Circumstances wherever lubrication is tricky 
or elongation of chain commonly takes place Remarks for use.
?Will not use this chain in dusty environments. In this kind of environments, use O-ring chains.
?This chain is to the use underneath light or medium load.Use O-ring chain when a substantial effect is applied to a chain.
?Set the chain feeding velocity at 150m/min. or decrease.
Collection of chains
As for sintered bushing roller chains, the inner plates are thicker and also the pins are longer than people of normal roller chains in order to compensate for that power lowered by the utilization of sintered bushings.
For deciding on a suitable chain, refer to “Selection of Chains”. Use the tables of greatest kilowatt ratings for sintered bushing roller chains that cover very low pace ranges.
For sintered bushing roller chains, “Low-speed selection” are not able to be utilized since the “Maximum allowable load” while in the dimension table considers only the chain tensile tension and neglects the bushing strength.
Connecting links and offset backlinks
For sintered bushing roller chain, R connecting back links are used for DID60 or smaller sized, and C connecting back links for DID80 or greater.
OJ can be used as offset hyperlinks. Please place an purchase the connecting hyperlinks and offset hyperlinks specifying the variety for sintered bushing roller chain.
During the tables of greatest kilowatt ratings, the strength in the connecting backlinks and offset links are taken under consideration.
Sprockets
Regular sprockets might be utilized for sintered bushing roller chains.
