SA3T/K M3 Male Thread Rod End Joint Bearing 3mm

The SA3T/K M3 Male Thread Rod End Joint Bearing (commonly known as a fisheye joint) is a high-precision self-aligning spherical slide bearing designed to handle radial and directional loads. Featuring an M3 external thread, this connector provides smooth, low-friction multi-directional rotation, making it an essential component for eliminating mechanical binding in complex linkages.

Constructed with a durable zinc-plated carbon steel body, a brass race, and a hardened chrome steel ball, this rod end joint ensures exceptional wear resistance and longevity. It is widely used in Delta 3D printers (such as Kossel builds), CNC machines, RC steering linkages, and custom robotics projects where precise, angular articulation is required. Its compact form factor and standard M3 threading allow for easy integration with standard threaded rods and carbon fiber tubes.

Features:

• Self-Aligning Design: Allows for angular misalignment and smooth multi-directional rotation without binding.
• Premium Construction: Zinc-plated carbon steel housing with a hardened chrome steel ball and brass race for high durability.
• Low Friction: Precision-ground internal ball joint ensures smooth movement and minimal backlash.
• Corrosion Resistant: Galvanized surface treatment protects the bearing from rust and environmental wear.
• Standard M3 Threading: Features a standard M3 x 0.5mm external (male) thread for easy compatibility with hobbyist hardware.
• Compact & Lightweight: Weighing only 4.6 grams, it is ideal for weight-sensitive applications like RC models and 3D printer effectors.
