Maintenance cost-free chains using sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain suitable to a place in which lubrication is tough. It makes use of bushings produced of the sintered alloy which impregnates lubricating oil.
To the use that calls for clean visual appeal, rustless type (URN) is accessible.
Advisable makes use of
?Conditions exactly where lubrication is difficult or elongation of chain usually takes place Remarks for use.
?Do not use this chain in dusty environments. In such environments, use O-ring chains.
?This chain is for that use under light or medium load.Use O-ring chain whenever a huge influence is applied to a chain.
?Set the chain feeding speed at 150m/min. or reduce.
Selection of chains
As for sintered bushing roller chains, the inner plates are thicker and also the pins are longer than these of typical roller chains in order to compensate for the power lowered by the use of sintered bushings.
For choosing an appropriate 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” can’t be utilised since the “Maximum allowable load” within the dimension table considers only the chain tensile stress and neglects the bushing power.
Connecting hyperlinks and offset hyperlinks
For sintered bushing roller chain, R connecting links are used for DID60 or smaller sized, and C connecting back links for DID80 or larger.
OJ might be made use of as offset backlinks. Please place an purchase the connecting backlinks and offset hyperlinks specifying the sort for sintered bushing roller chain.
Within the tables of highest kilowatt ratings, the power of your connecting backlinks and offset back links are taken under consideration.
Sprockets
Conventional sprockets can be employed for sintered bushing roller chains.
