Component Specifications

Definition
A clevis is a U-shaped mechanical connector typically made from forged or machined metal, featuring two parallel arms with aligned holes for a clevis pin or bolt. It forms a pivotal joint when assembled with a clevis pin and cotter pin or retaining ring, allowing rotational movement while transmitting tensile or compressive loads. Commonly used in linkage systems, control rods, and suspension assemblies where adjustable or detachable connections are required.
Working Principle
The clevis operates as a simple pivot joint by connecting two components via a pin through its U-shaped body. The pin acts as a rotational axis, allowing angular movement while the clevis arms distribute load evenly. When secured with a cotter pin or retaining mechanism, it prevents accidental disassembly while maintaining flexibility for maintenance and adjustment.
Materials
Typically carbon steel (AISI 1018, 1045), alloy steel (4140, 4340), stainless steel (304, 316), or aluminum alloys (6061-T6). Forged or machined with heat treatment (quenching and tempering) for strength. Surface treatments include zinc plating, galvanizing, or powder coating for corrosion resistance.
Technical Parameters
  • Finish Zinc-plated, hot-dip galvanized, or painted
  • Pin Diameter Standard sizes: 1/4", 5/16", 3/8", 1/2", etc.
  • Arm Thickness Varies by application (typically 3-20mm)
  • Load Capacity Rated by working load limit (WLL) and ultimate tensile strength (UTS)
  • Temperature Range -40°C to +200°C for standard materials
Standards
ISO 2341, DIN 71752, SAE J429, ASTM A307

Frequently Asked Questions

What is the difference between a clevis and a shackle?

A clevis has a U-shape with holes in both arms for a pin, designed for inline connections in linkages. A shackle typically has a rounded shape and is used for lifting or rigging with a screw pin or bolt-type closure.

How do you select the right clevis size?

Choose based on pin diameter (matching the rod end), load requirements (check WLL rating), material compatibility (environmental conditions), and arm thickness for the application's shear strength needs.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
