Perfect fit for my CNC project

The build quality is exceptional. The aluminum feels sturdy yet lightweight, and the keyway alignment was precise right out of the box. Highly recommended for servo applications.

Great for robotics

Used this on a robotic arm joint. The torque transmission is smooth and there is no backlash. Very satisfied with the performance and price point.

Good value, fast shipping

Works well for connecting my encoder motor. The variable diameter option made it easy to match my specific shaft sizes. Only minor issue was the instructions were a bit vague.

Solid performer

Does exactly what it says. The flexible discs absorb shock well during start-stop cycles. Would buy again if I need more units for my automation setup.

Excellent flexibility and durability

I've been running this coupling at high RPMs for weeks with zero vibration issues. The double disc design handles misalignment better than my previous rubber couplers.

5 FAQ

Q: What is the maximum RPM rating for the double disc version?

A: The double disc version is rated for up to 10,000 RPM depending on the specific bore size and balance. For speeds exceeding this, please contact our engineering team for customization.

Q: Does this come with the set screws needed for installation?

A: Yes, each package includes high-tensile set screws and an Allen key for immediate installation.

Q: Is the keyway standard metric or imperial?

A: We offer both metric and imperial keyway standards. Please specify your requirement in the order notes or choose the appropriate SKU variant.

Q: How much angular misalignment can this coupling compensate for?

A: The flexible disc design allows for approximately 1.5 to 2 degrees of angular misalignment, as well as minor parallel and axial offsets, ensuring smooth operation even if alignment isn't perfect.

Q: Can this coupling handle both 5mm and 8mm shafts?

A: Yes, this model supports variable diameters. Please select your specific bore sizes (e.g., 5mm-8mm) from the dropdown menu when ordering to ensure a perfect fit.
