Flexible Coupler (3mm to 6.50 mm)

Overview

This flexible coupler is an essential component for connecting a 3mm shaft to a 6.5mm shaft in precision mechanical systems. Its flexible design compensates for minor shaft misalignments, reducing stress on motors and bearings, and ensuring smooth, reliable power transmission. Ideal for CNC machines, 3D printers, robotics, and other automation projects, this coupler is built for durability and precision.

Key Features

• Flexible Design: Accommodates angular, parallel, and axial misalignments, protecting connected components.
• Secure Attachment: Includes two sets of set-screws to firmly lock both shafts in place.
• Precision Engineering: Machined to exact tolerances for minimal backlash and smooth operation.
• Versatile Sizing: Connects a 3mm shaft to a 6.5mm shaft, perfect for stepper motors and lead screws.
• Durable Construction: Made from high-quality materials to withstand demanding applications.

Technical Specifications

• Shaft Diameter (Input): 3mm
• Shaft Diameter (Output): 6.5mm
• Material: Aluminum alloy (or equivalent high-strength material)
• Fastening: Set screws (two sets included)
