Servicing cost-free chains applying sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain suitable to a place wherever lubrication is challenging. It makes use of bushings manufactured of a sintered alloy which impregnates lubricating oil.
To the use that involves clean appearance, rustless sort (URN) is obtainable.
Advised uses
?Conditions where lubrication is difficult or elongation of chain usually occurs Remarks for use.
?Never 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 when a massive effect is utilized to a chain.
?Set the chain feeding velocity at 150m/min. or reduce.
Collection of chains
As for sintered bushing roller chains, the inner plates are thicker and also the pins are longer than those of conventional roller chains in order to compensate for your power lowered by the utilization of sintered bushings.
For selecting an appropriate chain, refer to “Selection of Chains”. Make use of the tables of maximum kilowatt ratings for sintered bushing roller chains that cover low velocity ranges.
For sintered bushing roller chains, “Low-speed selection” cannot be utilized since the “Maximum allowable load” in the dimension table considers only the chain tensile stress and neglects the bushing power.
Connecting back links and offset back links
For sintered bushing roller chain, R connecting links are employed for DID60 or smaller sized, and C connecting backlinks for DID80 or bigger.
OJ might be utilised as offset back links. Please area an buy the connecting back links and offset hyperlinks specifying the variety for sintered bushing roller chain.
Inside the tables of maximum kilowatt ratings, the power of your connecting links and offset back links are taken under consideration.
Standard sprockets can be applied for sintered bushing roller chains.
