Upkeep cost-free chains using sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain appropriate to a place in which lubrication is difficult. It utilizes bushings created of the sintered alloy which impregnates lubricating oil.
To the use that demands clean appearance, rustless type (URN) is available.
Suggested employs
?Conditions wherever lubrication is challenging or elongation of chain commonly takes place Remarks for use.
?Don’t use this chain in dusty environments. In such environments, use O-ring chains.
?This chain is for the use underneath light or medium load.Use O-ring chain when a large effect is applied to a chain.
?Set the chain feeding speed at 150m/min. or lower.
Choice of chains
As for sintered bushing roller chains, the inner plates are thicker and also the pins are longer than those of regular roller chains so as to compensate for the strength lowered through the utilization of sintered bushings.
For selecting an appropriate chain, refer to “Selection of Chains”. Utilize the tables of maximum kilowatt ratings for sintered bushing roller chains that cover lower speed ranges.
For sintered bushing roller chains, “Low-speed selection” are unable to be made use of since the “Maximum allowable load” within the dimension table considers only the chain tensile tension and neglects the bushing strength.
Connecting hyperlinks and offset hyperlinks
For sintered bushing roller chain, R connecting backlinks are utilized for DID60 or smaller sized, and C connecting back links for DID80 or greater.
OJ is usually made use of as offset links. Please spot an buy the connecting back links and offset links specifying the style for sintered bushing roller chain.
While in the tables of greatest kilowatt ratings, the strength on the connecting back links and offset back links are taken into consideration.
Regular sprockets could be employed for sintered bushing roller chains.
