H class mill chains are of one-piece cast offset link construction joined together by steel clipped heads. They are used primarily for drag conveyor service in the lumber, pulp and paper industries. They are also desirable for transfer and conveying purposes.

Industries

Links are cast of high grade copper bearing malleable iron or Duramal. Duramal is a heat treated malleable iron having greater strength and superior resistance to wear and abrasion. Duramal chains have heat treated pins.

Riveted construction is furnished unless cottered construction is requested.

H class mill chains are interchangeable with other standard makes of corresponding sizes and numbers.

H class mill chains are used primarily for drag conveyor service in the lumber, pulp and paper industries. They are also desirable for transfer and conveying purposes. The pin joint permits operation in a moderately dusty or abrasive atmosphere.

The maximum speed of this chain is generally 450 FPM, but depends upon size of sprockets. For Drive Service see Table 10, Section A. For Conveyor Service see Table 2, Section A.
