U-Clevis

U-Clevis is a forged high-strength connecting component widely used in railway, power and heavy machinery industries. Made from carbon steel or alloy steel with hot-dip galvanized finish, it features a U-shaped double-hole structure for reliable chain or rod connection.
Designed to transmit tension and allow limited articulation, it ensures stable performance under heavy loads and harsh environments. With excellent wear resistance and anti-fatigue properties, it serves as a critical fastener for braking systems, power transmission lines and lifting equipment, meeting international industrial safety standards.

Product Description

▍Product Advantage

Forged Integrated Structure & Ultra-High Strength

Adopts precision hot forging process with one-piece molding, no welding cracks or deformation risks. This heavy duty U-Clevis has a breaking load up to 5-20T (customizable), featuring high tensile strength and excellent anti-fracture performance for heavy-load working conditions.

Premium Hot-Dip Galvanized Anti-Corrosion

Equipped with thick hot-dip galvanized coating (thickness ≥85μm), it delivers outstanding rust and corrosion resistance. Even in humid, outdoor or coastal harsh environments, its service life reaches 8-12 years, far longer than ordinary painted connectors.

Standardized Dimension & Easy Installation

Strictly manufactured per international sizing standards, with smooth hole positions and accurate spacing. It matches standard pins/shackles perfectly, realizing quick assembly and disassembly, saving 30% construction time and reducing labor costs.

Excellent Anti-Fatigue & Wear Resistance

After high-temperature quenching and tempering treatment, the hardness reaches HRC 25-32. It withstands long-term vibration and repeated pulling, avoiding fatigue damage and ensuring stable long-term operation.

Wide Compatibility & Strong Versatility

Suitable for various connection scenarios such as railway braking systems, power line fittings and lifting equipment. This forged U-Clevis supports custom sizes and load capacities to meet diverse industrial application demands.
