Webb Wheel Products, which manufactures hubs, brake drums and rotors for heavy-duty trucks and trailers, added its CRT (Cool Running Technology) vents to its latest advanced brake drum design, maximizing air flow into the wheel end to manage heat “10 percent better than similar drums,” the company said.
The Webb 56864B brake drum is optimized by using Finite Element Analysis and real-world data to run 10 percent cooler and last 10 percent longer in standard duty 23K drive and trailer applications.
With the drum’s heat transfer efficiency, maintenance costs will be reduced and brakes will perform better, Webb said.
Technology added to trailers to enhance aerodynamics, such as side skirts, also can reduce crosswind and straight-line airflow below the trailer, resulting in increases in brake temperature. This added heat reduces braking performance and accelerates brake drum and lining wear.
The design of the Webb 56864B brake drum with CRT vents helps mitigate the effects on your brakes from the deflected air flow around wheel-ends that may result from adding skirts or other similar bolt-on devices.
Webb brake drums are 100-percent designed, cast and machined in the US and backed by a nationwide warranty and Webb’s product support.
