H class cast chains
ZMIE “H” Class Cast Chain is an extremely strong, serviceable chain originally designed for heavy drives and transfer conveyor purposes in saw mills and the paper and pulp industry. “H” Class Cast Chain has proven itself for innumerable other industrial applications as well, especially for moderate duty in abrasive atmospheres where heavy, rugged chain is required.
The sidebars of the “H” Class links are reinforced with wearing shoes which strengthen and stiffen the links when it is operated in troughs or over floors and runways.
Pin holes are precision cored to assure accurate pitch sizes, which range from 2.308 to 4.000 inches. “H” Class Chain is available in both riveted and cottered construction. T-head pins engage two lugs cast on the links’ sidebars. This configuration prohibits pin rotation during chain operation, eliminating abrasive wear and pitch elongation.
ZMIE “H” Class Cast Chain conforms to manufacturer’s standards and is completely interchangeable with chains of other manufacturers. “H” Class Cast Chain is available in ZMIE Promal with tensile ranges of 9,450 to 40,500 pounds. “H” Class Cast Chain may operate in two directions. As a drive chain, it travels in the direction of the closed barrel; for elevator or conveyor applications, it should travel toward the open ends of the links.
