This triple-strand #200H roller chain meets ANSI B29.1 specifications, featuring thickened reinforced link plates for extreme heavy-load and high-torque transmission scenarios. All pins, bushings and rollers undergo professional heat treatment, delivering outstanding tensile strength, shock resistance and long wear life.
Precision machining effectively restricts chain elongation during prolonged heavy-duty operation, ensuring smooth engagement with matched triple #200H sprockets. It is ideal for large mining machinery, heavy bulk conveyors and heavy engineering equipment. Custom lengths, attachments and stainless steel alternatives are available upon inquiry.
