Servicing cost-free chains using sintered alloy bushings
Sintered bushing roller chain is maintenance-free chain ideal to a spot wherever lubrication is difficult. It employs bushings manufactured of the sintered alloy which impregnates lubricating oil.
To the use that requires clean appearance, rustless sort (URN) is available.
Advised employs
?Situations the place lubrication is difficult or elongation of chain usually takes place Remarks for use.
?Never use this chain in dusty environments. In this kind of environments, use O-ring chains.
?This chain is for that use below light or medium load.Use O-ring chain when a big influence is applied to a chain.
?Set the chain feeding pace at 150m/min. or decrease.
Variety of chains
As for sintered bushing roller chains, the inner plates are thicker and also the pins are longer than these of normal roller chains so as to compensate to the strength lowered from the use of sintered bushings.
For selecting an appropriate chain, refer to “Selection of Chains”. Utilize the tables of highest kilowatt ratings for sintered bushing roller chains that cover low speed ranges.
For sintered bushing roller chains, “Low-speed selection” cannot be used since the “Maximum allowable load” from the dimension table considers only the chain tensile stress and neglects the bushing power.
Connecting hyperlinks and offset back links
For sintered bushing roller chain, R connecting backlinks are made use of for DID60 or smaller, and C connecting links for DID80 or more substantial.
OJ could be made use of as offset backlinks. Please place an order the connecting back links and offset hyperlinks specifying the type for sintered bushing roller chain.
During the tables of maximum kilowatt ratings, the strength of the connecting links and offset back links are taken into consideration.
Standard sprockets might be applied for sintered bushing roller chains.
