Customized Fisheye Rod End Bearings: Threaded Ball Joint Forging Service

Product Overview

Our customized fisheye rod end bearings (threaded ball joints) are precision-forged components designed for high-load, high-misalignment applications in demanding mechanical systems. These forged rod ends provide superior strength, wear resistance, and smooth articulation, making them ideal for automotive, aerospace, industrial machinery, and hydraulic systems.

Key Features & Benefits

✔ High-Strength Forged Construction – Made from alloy steel, stainless steel, or titanium for exceptional durability and fatigue resistance.
✔ Precision Machining – Threaded shanks and ball sockets are CNC-machined to tight tolerances for smooth movement and secure fastening.
✔ Customizable Designs – Available in male/female threads, left/right-hand threads, and various bore sizes to match your application.
✔ Low-Friction Movement – PTFE-lined or self-lubricating options reduce wear and maintenance needs.
✔ Rigorous Quality Control – ISO 9001 & AS9100 certified, with hardness testing, dimensional inspection, and load testing.
