Decent but strict tolerance

The coupling works fine, but the shaft tolerance is quite tight. Make sure your motor shaft is precisely within spec, or it might be hard to install.

Perfect for my CNC upgrade

This coupling fits perfectly on my miniature stepper motor setup. The build quality is excellent, and the aluminum feels very durable without adding unnecessary weight.

Reliable and compact

Exactly what I needed for a tight space constraint. The D12L14 dimensions are accurate, and transmission efficiency seems high with no noticeable backlash.

Exceeded expectations

For the price, the quality is outstanding. The anodized finish looks professional, and it has been running continuously for weeks without any issues.

Good value, precise fit

Works well for parallel line connections in my small robot arm project. The elastic winding design handles minor misalignments smoothly. Only wish it came in more colors.

Great for precision instruments

Used this in a laboratory positioning device. It provides smooth rotation and effectively dampens vibration between the motor and the lead screw.

5 FAQ

Q: What is the return policy if the size doesn't fit my project?

A: We offer a 30-day return policy for unused items in their original packaging. If the coupling hasn't been installed or scratched, you can return it for a full refund or exchange.

Q: Is there any lubrication required before installation?

A: No, the coupling comes pre-finished and does not require additional lubrication. Simply ensure both shafts are clean and dry before inserting them into the coupling hubs.

Q: Can this coupling handle high-speed rotations above 5000 RPM?

A: While robust, this miniature coupling is optimized for precision and low-to-medium speed applications. For sustained speeds above 5000 RPM, we recommend consulting our industrial series for better balance and durability.

Q: Does this come with set screws for securing the shafts?

A: Yes, the package includes two small grub screws (set screws) and a matching Allen key to securely fasten the coupling to your motor and lead screw shafts.

Q: What is the maximum bore size this coupling can accommodate?

A: This specific model is designed for micro applications, typically accommodating shaft diameters ranging from 3mm to 5mm. Please check the detailed specification sheet for exact bore options available.
