Upkeep cost-free chains employing sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain ideal to a place in which lubrication is hard. It makes use of bushings manufactured of a sintered alloy which impregnates lubricating oil.
For the use that involves clean physical appearance, rustless sort (URN) is accessible.
Proposed uses
?Conditions in which lubrication is tough or elongation of chain often occurs Remarks for 
use.
?Do not use this chain in dusty environments. In such environments, use O-ring chains.
?This chain is for the use below light or medium load.Use O-ring chain whenever a big impact is utilized 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 plus the pins are longer than those of conventional roller chains so as to compensate for your strength lowered from the use of sintered bushings.
For choosing an appropriate chain, refer to “Selection of Chains”. Utilize the tables of optimum kilowatt ratings for sintered bushing roller chains that cover reduced speed ranges.
For sintered bushing roller chains, “Low-speed selection” cannot be applied because the “Maximum allowable load” in the dimension table considers only the chain tensile stress and neglects the bushing power.
Connecting backlinks and offset links
For sintered bushing roller chain, R connecting hyperlinks are utilised for DID60 or smaller, and C connecting hyperlinks for DID80 or larger.
OJ might be utilised as offset back links. Please spot an buy the connecting back links and offset back links specifying the type for sintered bushing roller chain.
Inside the tables of optimum kilowatt ratings, the power of your connecting links and offset backlinks are taken into account.
Sprockets
Typical sprockets can be applied for sintered bushing roller chains.
