Flexible Coupler (3mm to 5mm)

Overview

Connect your motor shafts with confidence using the MOKWN Flexible Coupler (3mm to 5mm). This precision-machined aluminum coupler is essential for any CNC, 3D printer, or robotics project, allowing you to join a 3mm motor shaft to a 5mm lead screw or shaft. It effectively compensates for slight misalignments, reducing stress on bearings and ensuring smooth, reliable operation.

Key Features

• Precision-Machined Aluminum: Durable and lightweight, providing excellent torsional rigidity.
• Flexible Design: Slotted cutouts allow for slight angular and parallel misalignment compensation.
• Secure Fit: Set screws firmly lock onto both shafts, preventing slippage.
• Versatile Sizing: Connects 3mm shafts to 5mm shafts, ideal for NEMA 17 stepper motors and lead screws.
• Corrosion-Resistant: Anodized or natural aluminum finish resists wear.
