High torque capacity
No slipping under heavy load. I use this for a Z-axis lift and it handles the weight without issue.

Solid build quality
Works great on my lathe upgrade. The aluminum feels sturdy and the anodizing is smooth. No vibration issues so far.

Perfect fit
Aligned my lead screw perfectly. The cross slider design handles the slight misalignment better than my old rigid coupling.

Good value
Shipping was slow but the item itself is excellent. Fits my stepper motor shaft perfectly.

Nice finish
Anodizing looks professional. One set screw was slightly tight but manageable. Overall satisfied.
Q: What is the screw thread size?
A: The included set screws are M3 thread size. Please use an appropriate hex key for installation.
Q: Is it compatible with NEMA 23?
A: Yes, if the shaft diameter of your NEMA 23 motor matches the bore size you select (typically 6.35mm or 8mm).
Q: Can this handle angular misalignment?
A: It is primarily designed for parallel misalignment compensation. For significant angular misalignment, a flexible beam coupling might be more suitable.
Q: Do I need to grease this?
A: It comes pre-lubricated from the factory. You do not need to add grease unless you disassemble it for cleaning.
Q: What bore sizes are available?
A: We offer 5mm, 6mm, and 8mm bore options. Please select your required size from the dropdown menu before ordering.
