3.17mm Brass Hex Shaft Coupling daier Flexible Coupler for DC Motors

Description

Product Overview

The daier 3.17mm brass hex shaft coupling is engineered to provide a robust, wear‑resistant link between motor shafts and hexagonal wheels. Constructed from premium brass, the coupling offers excellent corrosion resistance and long‑term durability, making it suitable for both hobbyist projects and professional applications. Its compact geometry—measuring 18mm in total height with a 7mm hex side—ensures a tight fit while allowing for slight misalignment, reducing stress on the motor and extending component life. The design incorporates a precision‑machined interior that aligns the motor shaft and driven wheel accurately, delivering smooth torque transfer without backlash.

Usage

This flexible coupler excels in a variety of environments. It is ideal for connecting DC motor shafts to hexagonal wheels in robotic arms, autonomous toy cars, and small‑scale industrial equipment. The coupling’s ability to absorb minor angular deviations makes it perfect for applications where vibration or slight misalignment is expected, such as in educational robotics kits, hobbyist model vehicles, and prototype machinery. Its high‑quality brass construction also makes it suitable for marine or outdoor projects where exposure to moisture could be an issue.
