Great for servo applications

Exactly what I needed for my robotic arm setup. The elastic element absorbs shocks well, protecting the motor bearings.

Good value for money

Works as expected. The aluminum feels sturdy, and the spider insert provides good vibration damping. Slightly tighter fit than anticipated but manageable.

5 FAQ

Q: What is the maximum misalignment angle this can compensate for?

A: The spider design allows for an angular misalignment compensation of approximately 1 to 1.5 degrees, ensuring smooth operation even if alignment isn't perfect.

Q: Is the spider insert replaceable if it wears out?

A: Yes, the elastomer spider insert is designed to be replaceable, allowing you to extend the life of the coupling without replacing the entire unit.

Q: What are the available bore sizes for this coupling?

A: We offer various bore sizes ranging from 5mm to 10mm. Please check the specific variant selection menu for available options.

Q: Does it come with set screws?

A: Yes, each coupling comes packaged with the necessary set screws for securing it to your motor shaft and lead screw.

Q: Can this handle high-speed rotations?

A: This coupling is suitable for moderate to high speeds typical in servo and stepper motor applications, usually up to 4000 RPM depending on the specific size.
