Great value for money

Compared to other brands, Zhe'ao offers great quality at a reasonable price. The anodized finish looks professional and seems resistant to corrosion.

Excellent torque transmission

I was worried about slippage under load, but this cross slider coupling handles the torque from my stepper motor without any issues. The eccentric compensation is smooth.

Solved my alignment issues

My motor and screw were slightly misaligned, causing vibration. This Oldham style coupling absorbed the misalignment perfectly, and now the machine runs silently.

Good quality, slight runout

The aluminum feels solid and the machining is clean. I noticed a tiny bit of runout at high speeds, but for standard 3D printer or engraver applications, it works flawlessly.

Solid construction

Very sturdy coupling. The only reason I didn't give 5 stars is that the instructions were minimal, but if you know how to install a clamp coupling, it's straightforward.

Perfect for my CNC upgrade

This coupling fits perfectly between my NEMA 23 motor and the lead screw. The clamp design makes installation very easy without needing set screws that might slip. Highly recommended for precision builds.

5 FAQ

Q: Can this handle axial thrust loads?

A: This coupling is designed primarily for torque transmission and misalignment compensation. It has limited axial thrust capacity; we recommend using separate thrust bearings for significant axial loads.

Q: Is this suitable for high-speed applications over 3000 RPM?

A: While durable, cross slider couplings are generally best suited for low to medium speed applications typical in CNC routers and 3D printers. For very high RPMs, we recommend checking our flexible disc coupling series.

Q: Does it come with screws for the clamps?

A: Yes, the package includes all necessary socket head cap screws required to tighten the clamp hubs securely onto your shafts.

Q: What shaft diameters does this coupling support?

A: This specific model is available in various bore sizes ranging from 5mm to 10mm. Please check the selection dropdown to choose the exact combination needed for your motor and lead screw.

Q: What is the maximum parallel misalignment tolerance?

A: The cross slider design typically allows for parallel misalignment up to 0.5mm depending on the specific size purchased. Refer to the technical drawing in the product images for precise tolerances per model.
