An Extensive Guide to DH-α Chain: A Superior Choice for Challenging Environments

The DH-α is a superior product designed to withstand harsh conditions such as dust, heat, and contamination. Its exceptional efficiency, strength, and longevity make it a reliable choice for various applications.

Unmatched Efficiency of the DH-α Chain

The DH-α Chain boasts a super-hard surface coating that protects important areas from adverse environments. It is designed to resist deterioration due to its oxidation and interaction with contaminants. Even under non-lubricated conditions and situations where dirt, dust, or fine metal particles may interfere, the DH-α Chain delivers outstanding performance.

Recommended Uses

  • Environments where soil, sand, or dust directly comes into contact with the chain. In such cases, O-ring chains are recommended if applicable.
  • Applications where a chain is lubricated in an oil bath and the oil is heavily deteriorated due to contamination with foreign objects.
  • Applications where it is necessary to prevent chain kinking from heat between the pin and bushing.

Characteristics and Selection of the DH-α Chain

The strength of the DH-α Chain matches that of standard roller chains. When choosing a suitable DH-α Chain, refer to our ‘Selection of Chains' guide. This chain also uses the same dimensions as conventional roller chains, allowing for ease of replacement and compatibility with standard sprockets.

Connecting Links and Offset Links

For the DH-α Chain, use the connecting links and offset links for standard roller chains. Even with multiple links, the numbers of connecting link and offset link remains minimal, therefore, their impact on the overall wear of the chain is negligible.
