Welded Steel Mill Chain Types
Welded steel mill chains, designed for heavy-duty industrial applications, are categorized into WR and WH Series, each tailored for demanding environments like forestry, mining, and lumber processing.
WR Series Welded Steel Mill Chain: The WR Series features heat-treated pins and case-hardened bushes, ensuring durability in abrasive conditions. Its welded construction, with offset sidebars, offers precise pitch control and smooth operation for moderate to heavy-duty tasks. These chains are ideal for conveying heavy loads in industries such as material handling and are available in riveted or cottered construction for easy assembly.
WH Series Welded Steel Mill Chain: The WH Series enhances strength by fully heat-treating all components, including sidebars, pins, and barrels, providing superior wear resistance and tensile strength. This rollerless chain excels in dusty environments, making it suitable for wood yards, paper mills, and ethanol processing. WH chains often feature induction-hardened components for extended service life and are interchangeable with standard makes.
Both series support various attachments and heat treatments, ensuring versatility and reliability in harsh industrial settings, with WH offering greater robustness for extreme conditions.
