Zero backlash confirmed
Critical for my positioning system, and this coupling delivers zero backlash as advertised. Installation was straightforward.

Excellent flexibility
Compensates well for slight misalignments in my setup. No noise during high-speed operations. Very satisfied with this purchase.

Perfect fit for my CNC project
The keyway alignment was precise, and the double disc design handles the motor torque without any vibration. Highly recommended for precision machinery.

Good quality, fast shipping
Solid aluminum construction. The anodized finish looks professional. Took off one star because the set screws were a bit tight to loosen initially.

Robust and reliable
Using this on a heavy-duty servo motor application. It has held up perfectly under continuous load for three months now.

Great value for money
Does exactly what it is supposed to do. The dimensions matched the spec sheet perfectly. Would buy again.
Q: Can I use this outdoors in rainy conditions?
A: The aluminum alloy has an anodized finish which offers some corrosion resistance, but we recommend protecting it from direct exposure to rain or harsh chemicals for longevity.
Q: Is there a single disc version available?
A: Yes, we stock both single and double disc variants. Please check the product options dropdown or contact us for a custom listing if you need the single disc model.
Q: How do I properly tighten the set screws?
A: We recommend tightening the set screws in a cross pattern to ensure even pressure on the shaft. Use a torque wrench if possible to avoid stripping the threads.
Q: What is the maximum RPM this coupler can handle?
A: While dependent on the specific bore size and balance, our standard aluminum double disc couplings are generally rated for speeds up to 4000 RPM safely.
Q: Does this coupling come with the keys for the keyway?
A: No, the keys are not included in the package. You will need to source standard keys matching your shaft diameter separately.
