Good value for money

Works well for the price point. The anodized finish looks professional. Just make sure you measure your shaft diameters carefully before ordering.

Solid build quality

The aluminum feels robust and the machining is precise. It handles the parallel misalignment in my setup without any vibration issues. Took off one star because the instructions were minimal.

Solved my alignment issues

My motor and screw were slightly off-center, and this Oldham coupling absorbed the error perfectly. No more grinding noises during operation.

Perfect for my CNC upgrade

This Oldham coupling fit perfectly between my stepper motor and lead screw. The clamping mechanism is very secure and eliminated the backlash I had with my old flexible coupling.

Reliable industrial component

Used these in a small automation project. They are easy to install and the zero-backlash feature is critical for our positioning accuracy. Highly recommended.

Great torque transmission

I was worried about slippage under high load, but this coupling holds tight. The eccentric design works exactly as described for my 3D printer Z-axis.

5 FAQ

Q: Does this coupling come in different bore sizes?

A: Yes, we offer various bore size combinations. Please check the specific variant options or contact us for custom sizing.

Q: Can this handle axial load?

A: Oldham couplings are primarily designed for torque transmission and parallel misalignment. They are not intended to support significant axial loads.

Q: What is the maximum RPM rating?

A: For standard aluminum alloy models, we recommend keeping operational speeds under 3000 RPM to ensure optimal balance and longevity.

Q: Is lubrication required for the sliding disk?

A: The center disk is self-lubricating in most standard applications, but light grease can be applied for high-speed or heavy-duty cycles to extend life.

Q: What tools are needed for installation?

A: You will typically need an Allen wrench (hex key) corresponding to the clamping screws on the coupling hubs.
