50mm Square Axle – Unbraked Lazy (Slimline Bearings)
Rating: 1450kg
Application: Heavy-duty single-axle trailers, boat trailers, and utility builds.
Product Overview
Engineered for durability and high load capacity, the 50mm square profile (solid beam) is the industry standard for unbraked trailer setups requiring a 1450kg rating. Featuring precision-machined Slimline (L68149/L12749) stubs, it provides a smooth, reliable tow for medium-to-heavy frames without the complexity of a braking system.
Key Features
- High-Grade Steel: Forged from premium solid square steel to prevent flexing under maximum load.
- Slimline Configuration: Uses the popular Slimline bearing set, offering a higher load rating than standard LM/Holden alternatives.
- Unbraked Simplicity: Perfect for trailers with a GVM under 750kg, or as a secondary axle in specific multi-configurations.
- Corrosion Resistant: Available in natural steel (for welding) or galvanised finishes (ideal for marine environments).
