Brass Oldham Coupling For 8mm Lead Screw Precise Z Axis Alignment Keeps It Tight On 3D Printers CNC Machined Low Friction Connection For CR10 S4 S5 Pro V2 CR10S Pro And Similar Models

Brass Oldham Coupling for 8mm Lead Screws, Precise Z Axis
✔️ 8mm lead screw brass Oldham coupling, center distance 18mm, M3 1pc

This brass Oldham coupling provides a tight, low-friction connection between an 8mm lead screw and the mount, keeping Z-axis alignment precise on 3D printers and CNC machines, including CR-10 series.

✅ Center distance between holes: 18mm, fixing hole M3, for 8mm lead screws
✅ Brass CNC-machined with tight tolerances for low friction
✅ High torsional stiffness to protect driven parts and bearings
✅ Improves Z-axis print quality by reducing bed sway from lead screw misalignment
✅ Compatible with Creality CR-10, CR-10S Pro, Ender 3 family and similar models

💡 What is an Oldham coupling used for in precision motion systems?

• Absorbs small angular and radial misalignment between shafts
• Brass CNC-machined body provides low friction and good torsional stiffness
• Handy for 8mm lead screw setups in printers and CNCs
• Helps keep drive trains stable, improving print quality
