Flexible Coupler (3mm to 3mm)

Overview

Ensure smooth and reliable power transmission in your CNC machine or 3D printer with the MOKWN Flexible Coupler (3mm to 3mm). This precision-engineered coupler is designed to connect a 3mm motor shaft to another 3mm shaft, accommodating slight misalignments that are inevitable in real-world assemblies. By absorbing vibrations and reducing bending stress, this coupler protects your motor and driven components, leading to longer equipment life and more accurate operations.

Key Features

• Precision 3mm to 3mm Connection: Specifically designed to connect two 3mm shafts, ensuring a secure and accurate fit.
• Misalignment Compensation: Absorbs parallel, angular, and axial misalignments, reducing stress on bearings and components.
• Vibration Damping: Flexible design absorbs vibrations, leading to smoother operation and reduced noise.
• Durable Construction: Made from high-quality materials for long-lasting performance in demanding applications.
• Easy Installation: Simple set-screw design allows for quick and secure mounting.
• Compact and Lightweight: Minimal added inertia, ideal for high-speed applications.

Technical Specifications

• Shaft Diameter (Connects): 3 mm to 3 mm
• Material: Aluminum alloy with flexible polymer insert (or specify if known)
• Length: Standard dimension (e.g., 20mm)
• Outer Diameter: Standard dimension (e.g., 15mm)
• Set Screws: 2 (one per shaft side)
• Weight: Lightweight (e.g., 10g)

Applications & Use Cases

• CNC Machines: Connect stepper motors to lead screws or ball screws for precise positioning.
• 3D Printers: Link stepper motors to threaded rods or lead screws in the Z-axis or extruder.
