3 Pack 6.35mm To 10mm Plum Flexible Shaft Couplings D25L30 Aluminum Jaw Spider Shaft Connectors For CNC Router Engraver Milling Machine And 3D Printer One Quarter Inch To 10mm Motor Adapter

Three-Pack Aluminum Shaft Couplings 6.35mm to 10mm for CNC
✔️ 3x aluminum jaw spider couplers, D25L30, 6.35mm to 10mm bores

These compact shaft adapters convert a 6.35mm (1/4") input shaft to a 10mm output shaft, featuring a robust aluminum body and a polyurethane spider cushion for vibration damping. They’re ideal for CNC routers, engraving machines, milling setups, and 3D printers where reliable motor-to-shaft connections are needed.

✅ 3-pack set includes three units for multi-axis projects or spares
✅ D25L30 dimensions: 25mm outer diameter, 30mm length
✅ 6.35mm (1/4") input to 10mm output bores for common motors
✅ Aluminum alloy body with polyurethane spider provides vibration damping
✅ Zero-backlash, high-precision machining for stable transmission
✅ Offset clamping screws allow quick, slip-free installation on NEMA 17/23 motors

💡 What is a shaft coupling used for in automation and how does it improve performance?

Handy parts that connect rotating shafts while keeping alignment tight and noise down.

- Maintains accurate motion in CNC routers, milling machines, and 3D printers - Dampens vibration for smoother operation and quieter runs - Quick, tool-free clamping on common motors like NEMA 17 and NEMA 23
