Timing belts are a lighter, more efficient alternative to chain. When installed correctly, timing belts require no tensioning. The HTD tooth profile results in a high strength power transmission that is suited for the high demanding loads of FRC robots.
The HTD belts have fiberglass tensile cord for superior strength, longevity and resistance to elongation.
The HTD belts come in a variety of sizes and widths to fit even the strictest design requirements.
All belts are neoprene coated fiberglass tensile cord.
