Drives® 81XHH chain is manufactured with heavier sidebars, through-hardened pins and solid rollers.
- Heavier Sidebars: 81XHH chain comes with heavier sidebars, leading to more bearing surface for conveying product. In addition, increasing sidebar thickness allows for welding to the inner link plate.
- Solid Rollers: Solid rollers allow for smoother engagement with sprockets and rotate freely to reduce pulsation in conveyors.
- Through-Hardened Pins: This chain comes with through-hardened pins, offering 20% higher tensile strength than case-hardened pins. We offer a CHP (chrome-hardened pin) upgrade that decreases wear between the pin and bushing, reducing elongation and increasing wear life.
If 81XHH isn’t what you’re looking for, we offer 81XH with a slightly smaller outside link plate. Our Kiln Dryer Series chains (81XKD, 81XHKD, and 3000KD) are also available for specific use on dryer or wallboard systems.
