These wheels can also withstand temperatures as low as -40°F. Our high-temperature phenolic wheels are made from a combination of resin and fiberglass to resist high temperatures while providing an impact-resistant wheel. Each wheel can withstand up to 600 lbs, but the capacities are rated for room temperatures.
If these are under maximum heat or cold for long periods, please reduce the weight capacity by 20%. The swivel caster that holds the wheel, also called the'rig' or'swivel yoke,' has a heat-treated double ball bearing raceway with a 5/8 kingpin bolt for strength and a zinc-plated coating for maximum rust and corrosion resistance.
