Structural Features & Manufacturing Technology

Clevis Pin for Mechanical Connection one-piece precision cold heading and centerless grinding forming process, consisting of a flat round limit head, smooth solid cylindrical pin body and reserved tail pin hole. The thickened flat head provides stable surface limiting, avoiding the pin body sinking into the mounting hole and ensuring consistent assembly flatness. The integral solid pin body has high structural rigidity and smooth surface finish, reducing friction resistance during component rotation and ensuring flexible and unobstructed mechanical movement. The precisely positioned tail hole has uniform aperture and smooth inner wall, perfectly matching standard split pins to form a complete safety locking system. Manufactured from high-quality carbon steel, alloy steel and stainless steel materials, all products undergo fine finishing, deburring and standardized anti-corrosion treatment. Strict dimensional tolerance control ensures zero-jitter fit with standard hinge holes, with stable shear resistance and long-term motion fatigue resistance, adapting to frequent movable assembly work conditions.

Core Advantages & Industrial Applications

1. Professional flat head limiting structure effectively prevents the pin body from sinking and shifting during high-speed rotation and reciprocating movement, maintaining stable assembly position of movable parts and avoiding mechanical jitter and connection deviation.

2. Tail hole locking matching design, perfectly compatible with standard split pins. The combination of clevis pin and split pin forms dual safety protection, completely solving the risk of pin body falling off caused by long-term mechanical vibration and impact load.

3. Ultra-smooth cylindrical pin body minimizes assembly friction, ensuring flexible and stable rotation of hinge joints and movable connecting parts. It has excellent motion fatigue resistance, not easy to jam or wear after long-term frequent operation.

4. High structural strength and strong shear resistance. The solid integral forming process enables the pin body to bear large lateral load and tension, adapting to heavy-duty movable connection scenarios of engineering machinery and vehicle equipment.

5. Clevis Pin for Mechanical Connection has wide application range with diversified material options, widely used in automobile chassis systems, agricultural machinery, hydraulic equipment, railway facilities, automation equipment and various mechanical hinge movable connection fields.
