flexible shaft coupler,
200.00৳ 250.00৳ (-20%)
This is a flexible helical shaft coupler, a precision hardware component used to connect two rotating shafts (like a motor and a lead screw).
Key Features
- Vibration Damping: The spiral “helical” cut allows the coupler to act as a spring, absorbing vibrations and reducing mechanical noise.
- Misalignment Correction: It compensates for slight angular and parallel offsets between shafts, preventing damage to motor bearings.
- Zero Backlash: Its one-piece aluminum construction ensures accurate motion transmission with no “play” or lost motion.
- Lightweight & Durable: Made from high-grade aluminum, it is corrosion-resistant and maintenance-free.
Common Uses
- 3D Printers: Most commonly used on the Z-axis to connect stepper motors to lead screws.
- CNC Machines: Used for connecting encoders and motors to driving shafts.
- Robotics: General-purpose motion transfer in DIY electronics projects.
Standard Dimensions: Typically 19mm in diameter and 25mm long (D19L25), with common bore sizes like 5mm x 5mm or 5mm x 8mm.

flexible shaft coupler,
This flexible helical shaft coupler is a high-precision, one-piece hardware component designed to connect two rotating shafts while managing minor misalignments. It is a critical part in motion control systems like 3D printers and CNC machines, where it typically links a stepper motor to a lead screw.

Key Product Features
- Helical Beam Design: The spiral-cut pattern allows the coupler to act as a spring in multiple directions (X, Y, and Z axes), which effectively dampens vibrations and reduces mechanical noise.

- Zero Backlash: This one-piece construction ensures that rotational motion is transmitted accurately with no “play,” making it ideal for precision work.
- Misalignment Compensation: It is specifically engineered to handle angular (up to 5°), parallel, and axial offsets between shafts, which prevents binding and reduces stress on motor bearings.
- High-Grade Material: Most standard models are machined from 7075-T6 aluminum or other high-strength aluminum alloys, providing a lightweight, corrosion-resistant, and maintenance-free solution.
