Dura-Light Hubs® for Drum Brakes
The Preferred Hub for 2″ Offset wheels & Wide-based, Single Tires
In keeping with Walther EMC’s heritage of bringing innovative products to our customers, we have been busy making the industry’s lightest hubs even lighter!
Our engineers have used the latest technology to optimize the hub designs – enabling us to eliminate material where it is not needed. This provides the ideal amount of material in the critical areas, giving you optimal performance.
The five-pilot geometry of our Dura-Light Hubs® reduces stress concentrations in the critical areas. The end result is a lighter hub that is even stronger than our previous generation.
Dura-Light Hub® Features & Benefits:
- Low cost
- More freight capacity for entire trailer life; helps offset recent increases in tractor weight
- Improved fuel economy – lower rotational inertia
- No future costs to maintain weight savings; i.e. high replacement cost of light-weight brake drums
- Trailer more valuable because light-weight (resale)
- Life-of-the-Vehicle Warranty
- Weight reduction without trailer life compromise
- Utilizes industry standard components – bearing cups, seal, hub cap and hub cap bolts
- Utilizes industry standard procedures for maintenance
- Virtually impossible to strip hub cap bolt hole threads
- Industry-leading lubricant capacity extends bearing and seal life
- No Aluminum Hub Maintenance Risks
Dura-Light Hub® Rotor Assemblies for Air Disc Brakes
The Perfect Balance of Weight, Functionality, and Value
We’ve been at it again! This time we’ve set our sights on bringing superior value to air disc hub and rotor assemblies with our new Dura-Light Hub® and Rotor Assemblies for trailer applications.
Our engineers have used the latest technology to optimize the hub designs – enabling us to eliminate material where it is not needed in the hub. We used a portion of this weight savings to put extra material in the rotor to resolve common field complaints with competitive products. Our simple construction which utilizes the wheel bolts for attaching the rotor eliminates rotor retention concerns and optimizes heat flow to keep your seals, bearings, and lubricant running cooler! Our second generation CR-ABS™ tone ring attachment system reduces ABS tone ring retention and corrosion issues!
Dura-Light Hub® and Rotor Features & Benefits:

- Ductile Iron = 32 W/m°K
- Aluminum A356 T6 = 151 W/m°K
- Simplicity / Ease of Maintenance
- Rotor affixed to hub using wheel bolts (aka the Strongest Joint on the Vehicle)
- Wheel bolts can be serviced without removing hub from vehicle
- Low Cost
- More freight capacity for entire trailer life; helps offset recent increases in tractor weight
- Improved fuel economy – lower rotational inertia
- Weight reduction without trailer life compromise
- Utilizes industry standard components – bearing cups, seal, hub cap and hub cap bolts
- Virtually impossible to strip hub cap bolt hole threads
- Industry-leading lubricant capacity extends bearing and seal life
- No Aluminum Hub Maintenance Risks
- Indestructible Hub pilots
- E-coated inside and out (cleanest cavity)
- No heat to service cups
- Patented features protected under United States Patent Numbers 7,780,367 & 8,584,815
