H class mill chain is a type of roller chain that is commonly used in heavy-duty industrial applications, such as steel mills, lumber mills, and other processing plants. The "H" in the name refers to the fact that the chain is designed to handle heavy loads and high shock loads.

H class mill chains are typically made of high-strength carbon steel and have large, solid rollers that provide a smooth, consistent motion as the chain moves along its sprockets. The pins and bushings are also made of high-strength materials to ensure durability and resistance to wear and fatigue.

These chains are often used in applications that require high strength and reliability, such as in conveyor systems, transfer equipment, and other heavy machinery. They are also used in situations where harsh environmental conditions or high temperatures are present, as they are able to withstand these conditions without losing strength or flexibility.

H Class Mill Chain Features

The "H" Class Mill Chains were originally designed for heavy-duty tasks in saw mills, paper, and pulp industries. However, due to their strength and durability, they have found many other industrial applications, particularly in abrasive atmospheres where robust chains are necessary. The "H" Class links have sidebars that are reinforced with wearing shoes, making them even stronger when operated in troughs or over floors and runways.

The pin holes in the "H" Class Chain are precisely cored to ensure accurate pitch sizes, which range from 2.308 to 4.000 inches. Both riveted and cottered constructions are available. The T-head pins engage two lugs on the links' sidebars, preventing pin rotation during chain operation, which eliminates abrasive wear and pitch elongation.
