Trailer Axle

A trailer axle serves as the central load-bearing shaft that connects the wheels and transfers the trailer's cargo weight onto the ground, playing a fundamental role in both structural support and ride dynamics. There are primarily two axle systems: spring (leaf-spring) axles and torsion axles. Spring axles use leaf spring packs mounted beneath or above the beam, offering robust, cost-effective suspension with straightforward maintenance and parts replacement. Torsion axles encapsulate individual trailing arms and rubber cords inside a sealed tube, delivering independent suspension and smoother ride quality with fewer metal-on-metal wear points. Axles can be straight for even deck height, drop-style to lower load-leveling, or overslung/underslung depending on clearance and stability requirements. They are available in configurations ranging from single to tandem or triple axles, depending on weight distribution needs.
