Flexible Coupler (4mm to 5 mm)

Overview

Connect your motor shafts with confidence using this precision-machined aluminum flexible coupler. Designed to bridge a 4mm motor shaft to a 5mm driven shaft, this coupler is an essential component for CNC routers, 3D printers, and robotics projects. Its flexible design compensates for minor misalignments, reducing stress on bearings and ensuring smooth, accurate motion.

Key Features

• Precision Machined Aluminum: High-quality aluminum construction ensures durability and lightweight performance.
• Flexible Design: Absorbs vibration and compensates for angular and parallel misalignment, protecting your equipment.
• Set-Screw Fastening: Two set screws on each side provide a secure, reliable grip on both shafts.
• Versatile Sizing: Ideal for connecting 4mm motor shafts to 5mm lead screws or other shafts.
• Corrosion Resistant: Anodized finish (if applicable) or natural aluminum resists wear and tear.
