Flexible Coupler (5mm to 6.5mm)

Overview

This flexible coupler is an essential component for connecting a 5mm motor shaft to a 6.5mm shaft in your mechanical projects. Its spiral-cut design provides flexibility, effectively accommodating minor misalignments that can occur during assembly or operation. Whether you're building a CNC machine, a robotic arm, or any precision-driven project, this coupler ensures reliable torque transmission while reducing stress on connected components.

Key Features

• Flexible Spiral Design: The spiral cut allows for slight angular, parallel, and axial misalignment, reducing wear on motors and shafts.
• Secure Connection: Includes two sets of set screws to firmly lock the coupler onto both shafts.
• Versatile Sizing: Specifically designed to connect a 5mm shaft to a 6.5mm shaft, common in NEMA motors and lead screws.
• Durable Construction: Made from high-quality aluminum alloy, offering strength and corrosion resistance.
• Easy Installation: Simple to mount with basic tools; no special equipment required.

Technical Specifications

• Bore Diameter 1: 5mm
• Bore Diameter 2: 6.5mm
