The pin with a super-hard
surface coating
protects the important spot
from adverse environments
Excellent lubrication can make chain existence longer. It truly is not uncomplicated in order to avoid deterioration on account of its personal oxidation and mixture with contaminants. In this case, DH-αchain shows very good performance. Superb functionality may be anticipated below non-lubricated situations and in this 
kind of essential problems in which filth, dust or fine metal particles get the job done into the chain.
Advisable uses
?Environments exactly where soil, sand or dust directly comes
into get in touch with using the chain (O-ring chains are encouraged if applicable.).
?Applications where a chain is lubricated in an oil bath and also the oil is heavily deteriorated as a result of the contamination of foreign objects.
?To prevent chain kinking by heat among pin and bushing
Selection of chains
The strength of DH-αchain could be the same as that of normal roller chains. For choosing a suitable DH-α chain, refer to “Selection of Chains” .
Connecting backlinks and offset back links
Utilize the connecting back links and offset back links for typical roller chains. Even though a chain has quite a few hyperlinks, the numbers of connecting hyperlink and offset hyperlink is one or two, and, hence, their influence to the wear on the whole chain is small.
Sprockets
The dimensions of DH-αchain could be the similar as those of typical roller chains. Use conventional sprockets for standard roller chains.
