Maintenance totally free chains utilizing sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain suitable to a spot wherever lubrication is tricky. It utilizes bushings made of a sintered alloy which impregnates lubricating oil.
To the use that requires clean appearance, rustless sort (URN) is accessible.
Recommended utilizes
?Circumstances wherever lubrication is challenging or elongation of chain usually takes place Remarks for use.
?Do not 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 when a massive impact is applied to a chain.
?Set the chain feeding speed at 150m/min. or reduced.
Choice of chains
As for sintered bushing roller chains, the inner plates are thicker as well as pins are longer than these of typical roller chains so as to compensate to the power lowered by the use of sintered bushings.
For picking out an appropriate chain, refer to “Selection of Chains”. Utilize the tables of maximum kilowatt ratings for sintered bushing roller chains that cover low velocity ranges.
For sintered bushing roller chains, “Low-speed selection” are not able to be employed because the “Maximum allowable load” during the dimension table considers only the chain tensile tension and neglects the bushing power.
Connecting hyperlinks and offset backlinks
For sintered bushing roller chain, R connecting backlinks are utilised for DID60 or smaller sized, and C connecting links for DID80 or larger.
OJ could be made use of as offset links. Please place an purchase the connecting backlinks and offset backlinks specifying the sort for sintered bushing roller chain.
During the tables of maximum kilowatt ratings, the strength with the connecting hyperlinks and offset hyperlinks are taken under consideration.
Sprockets
Normal sprockets might be applied for sintered bushing roller chains.
