Webb Wheel OEM says it has redesigned its 25,000 pound 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, 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, the company says.
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 pounds 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. Webb says.
