Trade Information

Trailer U-bolt is the core fastener of semi-trailer suspension, used to lock leaf springs to axle seats and directly determine suspension stability, widely matched with freight and heavy mine semi-trailers.
Material & Process: High-quality solid 45# steel integrally hot-forged and bent without welding joints. Quenching and tempering heat treatment eliminates internal stress to improve tensile and fatigue resistance, no crack or thread slip under continuous heavy load on rough mine roads.
Thread Structure: Extended full-length thread provides ample vertical adjustment stroke for different thickness leaf spring assemblies. Precision rolled deep wear-resistant threads matched with thick hex anti-loose nuts avoid loosening during high-speed downhill bumping.
Matching Press Plate: Thick stamped press plate with large contact area distributes clamping pressure evenly, preventing leaf spring crack and deformation from single-point extrusion and extending spring service life.
Application Range: Standard sizes fit 13t/16t American trailer axles, universal for flatbed, container, tipper, low-bed and curtain side trailers. Inner U width, screw diameter and total length can be customized according to leaf spring width, larger diameter bolts available for heavy mine trailers.
Supply Advantage: Mass forged production by standardized assembly line with unified thread precision and strong part interchangeability for easy overseas maintenance. Complete sets include U-bolt, press plate and double nuts, palletized packaging suitable for bulk container shipment, favorable bulk price for complete trailer matching, full tensile force inspection certificates and export documents provided.
