An M4 SA4PK bearing is a male rod end ball joint bearing featuring a 4mm bore and an M4 right-hand thread, designed for self-aligning, low-friction motion in 3D printers and robotics. Key features include a steel construction with a PTFE-lined (synthetic) outer sphere for reduced friction, a design that allows for automatic alignment and stable connections, and a right-hand thread for easy, secure tightening.
Features
- M4 Male Thread: The bearing has a male external thread with a 4mm diameter (M4) for connecting to components.
- Right-Hand Thread: The thread is designed to be tightened on the right-hand side.
4mm Bore: The central hole (bore) of the bearing is 4mm, which is the size of the rotating ball.
- Steel Construction: The body of the bearing is made from metal or steel, providing durability.
- PTFE Lined Outer Sphere: The inner ball rotates within a self-lubricating PTFE (synthetic) liner. This maintenance-free feature reduces friction and wear.
- Self-Aligning Design: The internal ball and outer ring are not fixed, allowing the bearing to automatically align itself to the rod's position.
- Fisheye Bearing: The self-aligning, ball-joint design is also known as a fisheye bearing, which is crucial for ensuring precise articulation in robotic and 3D printer motion control.
- Applications: Commonly used in 3D printers, robotics, and CNC equipment for stable connections and smooth, precise movement.
