Servicing totally free chains applying sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain ideal to a area where lubrication is difficult. It makes use of bushings made of a sintered alloy which impregnates lubricating oil.
To the use that needs clean physical appearance, rustless type (URN) is available.
Advised utilizes
?Conditions where lubrication is tricky or elongation of chain often happens Remarks for use.
?Do not use this chain in dusty environments. In such environments, use O-ring chains.
?This chain is for that use underneath light or medium load.Use O-ring chain whenever a big impact 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 as well as pins are longer than those of common roller chains in order to compensate for that strength lowered by the use of sintered bushings.
For selecting an appropriate chain, refer to “Selection of Chains”. Use the tables of highest kilowatt ratings for sintered bushing roller chains that cover minimal pace ranges.
For sintered bushing roller chains, “Low-speed selection” cannot be utilised since the “Maximum allowable load” in the dimension table considers only the chain tensile tension and neglects the bushing power.
Connecting hyperlinks and offset hyperlinks
For sintered bushing roller chain, R connecting links are applied for DID60 or smaller, and C connecting backlinks for DID80 or more substantial.
OJ may be made use of as offset links. Please area an order the connecting backlinks and offset hyperlinks specifying the kind for sintered bushing roller chain.
In the tables of optimum kilowatt ratings, the strength of your connecting hyperlinks and offset back links are taken under consideration.
Sprockets
Typical sprockets can be used for sintered bushing roller chains.
