Webb Wheel OEM has redesigned their 25,000-lb axle-rated TN trailer hub to make it lighter and to simplify brake drum installation.
The new patent pending design of Webb 2023 TN trailer hub includes a scalloped flange which reduces the overall weight. By incorporating ten total drum pilots (five combination wheel/drum pilots and five individual drum pilots) which are radially aligned with the studs, Webb’s new design reduces the probability of non-concentric mounting by reducing the frictional forces between the hub and drum during the assembly process. Webb also added an oil plug pad, which has been relocated and angled increasing accessibility of the plug after wheel installation. The new 2023 hub weighs 3.5 lbs less than the previous design, resulting in the lightest ductile iron hub available for 25K-rated TN trailer axles.
The new Webb TN trailer hub is a direct replacement for all current 2123 and 2023 hub applications. All future production will incorporate the redesigned elements.
