Webb Wheel Products has introduced a new brake drum to its wheel end portfolio of products, optimized for use in trailer applications.
The drum is lighter and designed to run cooler with Webb’s Cool Running Technology vents. It was engineered specifically for 20,000-pound trailer axles. Data suggests that aerodynamic trailer skirts can increase brake temperatures by reducing airflow beneath a trailer, according to Webb. The increased head reduces braking performance and accelerates brake drum and lining wear.
The Webb 66764F brake drum with CRT vents increases airflow for better heat transfer efficiency and cooler trailer wheel-end operating temperatures, managing heat 10% better than similar weight brake drums.
The 66764F brake drum also provides a high strength to weight ratio, weighing in at 99 pounds, which Webb says is the lowest weight in its class.
“The push to increase trailer aerodynamics has created opportunities for trailer component suppliers to design products that recognize how these new technologies can change overall trailer functions,” said Johnathon Capps, vice president of engineering. “Our experience with designing and producing cooler running brake drums directed us to a solution that mitigates the impact of higher brake temperatures caused by the change in air flow.”
