CBXA AeroBeam Series

for Fixed Frame Trailer
Air Suspension Axle Systems

The Industry's Lightest Weight Air Suspension Systems!

The new CBX AeroBeam line of fixed frame suspensions offers the best in top mount design technology with 23k, 25k and 30k capacity models. And when equipped with optional P89 disc brakes, the series provides the lightest weight fixed frame air suspensions available. The versatile model range meets most vocational fleet applications with the CBXAN23 model being the ideal solution for tank, platform and bulk transport trailers.





The new, industry’s lightest CBXAN23 AeroBeam suspension is the ideal solution for tank and platform trailers.

Designed specifically for tank and platform trailer applications, the industry’s lightest weight fixed frame suspension means maximizing your payload every time you transport. Lightweight without sacrificing durability, the suspension features high strength cast steel trailing arms with an axle that is 19% more rigid than the closest competitor to prevent premature tire wear. Optional SAF disc brakes or standard drum brakes available for the best in brake technology. Frame brackets available in taper top for platform trailers and weld-on with wing, and stainless weld-on styles for tank trailers. Specify our super lightweight disc brake wheel end and save 62 pounds per axle, that’s a whopping 124 pounds per tandem configuration.

Tire Pilot Plus™

Improve Profitability by Enhancing Tire Life, Fuel Efficiency and Uptime

Optional Tire Pilot Plus™ not only controls pressure through inflation, but also maintains equal pressure across all wheels and features high pressure relief for overinflated tires.

The robust design sets it apart from competitive designs with durable components.

Proper Air Pressure is Critical to Tire Life

Full Contact
Optimizes traction, handling and maximizes tire life.

Outside Contact
Accelerates irregular tread wear, increases rolling resistance, and reduces fuel efficiency by up to 2%.

Center Contact
Only reduces tire life and traction. Tire is susceptible to tread damage and punctures.

Installation Procedures

Troubleshooting Procedures


Cast Beam Technology

Lightweight cast steel trailing arm beam design meets the demand for durability while providing a low overall system weight.


Fastest and Most Convenient Axle Alignment System in the Industry

No replacement parts or disassembly is required. Axle alignment adjustment is made directly by the lead screw, and requires less than 250 ft. lbs. of torque to adjust.

  • No loosening, re-torquing, or rebuilding the pivot connection
  • No replacement parts
  • Saves 2-hrs in shop labor time and $50 in replacement parts over competitor’s alignment systems

Multi-Functional Pivot Bushing

SAF CBXA series fixed frame trailer air suspensions feature a patented, multi-functional pivot bushing with an exclusive external void design that extends the life and performance of the bushing when compared to the life of the internal void bushing design found in competitive suspensions.

Significant Bottom Line Savings

  • Fewer Axle Alignments
  • Reduced Tire Wear
  • Decreased Fuel Consumption
  • Increased Suspension Component Life
  • 7-Year Warranty

When driving over potholes, expansion joints, curbs, as well as, accelerating and braking.

Design Performance: With more mass along the bushing front and rear, fore and aft movement is minimized.

Design Benefit: Axle alignment is preserved, maximizing tire life and fuel mileage.


When trailer shifts from side to side while cornering, changing lanes, hitting potholes, or during curb strikes.

Design Performance: The external void design, allows the bushing to flex, keeping the tires in contact with the road surface.

Design Benefit: This is critical to roll stability and vehicle handling, as well as for prolonging tire life.


When driving on uneven road surfaces, and while cornering or changing lanes.

Design Performance: Strategically placed external voids at the bushing top and bottom, allows the bushing to more easily compress vertically.

Design Benefit: Improved ride quality and less stress on the trailer frame and suspension components.


When suspension moves up and down during normal daily operations.

Design Performance: The external void design, fairs better over time than an internal void design that tends to fatigue and crack.

Design Benefit: Longer life and unmatched durability for reduced maintenance costs over the life of the suspension.

Self-Steering Axle

Proven Performance with SPIF Compliance, It's Reason Enough.

Black Armour

The Most Advanced Suspension Corrosion Protection Available!

Black Armour™

Standard on all SAF Suspensions

Protect your fleet and your bottom line when you spec a CBXA series fixed frame air suspension system that comes standard with the exclusive Black Armour™ corrosion protection treatment.

This advanced corrosion protection gives you the ultimate defense against rust and corrosion.

… Only from SAF-HOLLAND

  • Factory applied on ALL CBXA fixed frame suspensions
  • Weighs and cost significantly less than hot-dip galvanization
  • Can be used as a finish coat or a primer

A Unique Chemical Treatment – Not Just Another Paint or Coating!

Black Armour™ metal treatment is the perfect foundation for fleets that want to add their own topcoat. It can act either as a topcoat, or a primer for nearly any topcoat, all without additional sanding or prep work.

Black Armour™ is a water-based zinc-free coating with 72% fewer solvents than traditional coatings and fewer VOCs!

Black Armour™ is not just a paint – it grafts with metal to form a protective skin that will not shrink or peel, and is impervious to moisture and today’s harsh, anti-icing agents. Unlike paints and powder-coats, Black Armour™ prevents rust creep should chipping occur.
