Upkeep totally free chains making use of sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain appropriate to a location the place lubrication is complicated. It uses bushings produced of a sintered alloy which impregnates lubricating oil.
To the use that requires clean physical appearance, rustless kind (URN) is accessible.
Suggested utilizes
?Conditions wherever lubrication is tricky or elongation of chain often occurs Remarks for use.
?Don’t use this chain 
in dusty environments. In such environments, use O-ring chains.
?This chain is for your use underneath light or medium load.Use O-ring chain whenever a significant effect is applied to a chain.
?Set the chain feeding velocity at 150m/min. or lower.
Selection of chains
As for sintered bushing roller chains, the inner plates are thicker and also the pins are longer than those of common roller chains in order to compensate to the strength lowered by the use of sintered bushings.
For picking a suitable chain, refer to “Selection of Chains”. Use the tables of optimum kilowatt ratings for sintered bushing roller chains that cover minimal speed ranges.
For sintered bushing roller chains, “Low-speed selection” can’t be used because the “Maximum allowable load” within the dimension table considers only the chain tensile stress and neglects the bushing power.
Connecting links and offset back links
For sintered bushing roller chain, R connecting links are made use of for DID60 or smaller sized, and C connecting hyperlinks for DID80 or bigger.
OJ may be used as offset hyperlinks. Please location an buy the connecting hyperlinks and offset backlinks specifying the style for sintered bushing roller chain.
From the tables of greatest kilowatt ratings, the strength in the connecting backlinks and offset back links are taken under consideration.
Sprockets
Standard sprockets can be utilised for sintered bushing roller chains.
