5 FAQ

Q: Is it compatible with stepper motors or only servos?

A: While optimized for servo motors due to the zero-backlash requirement, it works perfectly with stepper motors as well, provided the shaft diameters match the coupling bore.

Q: How do I determine the correct bore size for my application?

A: Please measure your motor and load shaft diameters precisely. We offer custom boring services; simply select the 'Custom Bore' option at checkout and specify your dimensions in the notes.

Q: Does this coupling require lubrication during installation?

A: No, this aluminum alloy coupling is designed to be maintenance-free and does not require lubrication. Ensure the shafts are clean and dry before tightening the set screws.

Q: Can this handle axial movement if the motor expands due to heat?

A: Yes, the parallel slit groove design allows for approximately 0.8mm of axial displacement, which accommodates thermal expansion in most standard servo motor applications.

Q: What is the hardness rating of the aluminum used?

A: We use Aluminum Alloy 7075-T6, which has a Brinell hardness of approximately 150 HB, offering an excellent balance between strength and weight.
