Flexible Coupler (3mm to 6.35mm)

Overview

The Flexible Coupler (3mm to 6.35mm) is a precision-engineered mechanical component designed to connect motor shafts of different diameters (3mm and 6.35mm) while accommodating minor misalignments. Its spiral-cut design provides the flexibility needed to absorb vibration and reduce stress on connected equipment, ensuring smooth and reliable operation in CNC machines, 3D printers, and other precision-driven applications. This coupler comes with set screws for a secure and easy installation, making it a versatile and essential addition to your motion control setup.

Key Features

• Dual-Shaft Compatibility: Connects a 3mm shaft to a 6.35mm shaft, bridging the gap between different motor and lead screw sizes.
• Spiral-Cut Flexibility: The helical cut allows for angular, parallel, and axial misalignment compensation, reducing wear on bearings and shafts.
• Secure Grip: Equipped with set screws that firmly lock the coupler onto both shafts, preventing slippage during operation.
• Precision Machining: Manufactured to tight tolerances for minimal backlash and high torque transmission.
• Durable Construction: Made from high-quality aluminum alloy, offering a balance of strength and lightweight performance.
• Easy Installation: Simple design requires only a hex key to tighten the set screws—no special tools needed.
