This 50mm Square 3t Unbraked Axle is an ultra-heavy-duty solution designed for the most demanding trailer applications.

Engineered to handle a massive 3,000kg (3t) rating, this axle is the perfect foundation for heavy plant trailers, livestock hauliers, and specialised machinery trailers where independent braking is managed by other axles in a multi-axle setup.

Product Overview

When 2-tonne axles aren’t enough, this 3t square beam provides the ultimate in structural integrity. Manufactured from premium, high-tensile K1045 steel, it features oversized spindles specifically designed to accommodate 3-tonne bearing sets. Available in both 5-stud and 6-stud Land Cruiser patterns, it allows you to match the heavy-duty rims and tyres required for 3,000kg loads.

Key Features

Extreme Load Capacity: Rated for 3,000kg (3t), making it one of the strongest unbraked axle options available for custom trailer builds.
Solid 50mm Square Beam: Forged from structural-grade K1045 steel to resist bowing and torsional stress under maximum weight.
3t Specific Spindles: Features precision-machined, oversized spindles designed to house large-diameter 3t tapered roller bearings.
LandCruiser Stud Patterns: Choice of 5-stud or 6-stud (139.7mm PCD) patterns, pre-pressed with high-tensile 5/8″ or 1/2″ studs to suit off-road 4WD wheels.
Lazy Hub Configuration: Supplied with heavy-duty “lazy” hubs (unbraked), providing a clean and simplified setup for tandem or tri-axle trailers.

Why Choose a 3t Square Axle?

Standard 50mm axles are typically capped at 2,250kg. This 3t version utilises specialised heat-treatment and larger spindle diameters to bridge the gap for heavy-duty industrial and agricultural use. It ensures your trailer chassis remains stable and your bearings stay cool even under extreme stress.
