Rod End Bearing M3 Female - SI3T/K

This SI3T/K rod end bearing is a mechanical articulating joint, generally used on the ends of control rods, steering links or tie rods. A ball swivel with a 3mm hole is pressed into a circular housing with an M3 female threaded shaft attached. The 3mm opening of the ball swivel is where one connects a bolt or other hardware, enabling the precision articulated joint movement.

Delta style 3D printers use six of these which attach to the hot-end effector unit.
