Excellent torque transmission

Used this for a high-torque application in a robotic arm. No slippage and no vibration. The rigid design provides the stability I needed for precise movements.

Perfect for my CNC upgrade

This brass coupling fits perfectly on my servo motor setup. The zero-backlash claim holds true, and the machining precision is evident immediately upon installation.

Works as described

Good product overall. The elastic properties help dampen minor misalignments while maintaining rigidity. Shipping was fast and packaging protected the polished finish well.

Precision engineering

I am impressed by the balance of this coupling. It runs smoothly at high RPMs without generating excess heat. Highly recommended for encoder applications.

Solid build quality

Very heavy and well-made. The brass material looks premium. I deducted one star only because the set screws were slightly tight to thread initially, but they hold very well now.

Great value for money

Compared to steel couplings, this brass version offers great corrosion resistance for my workshop environment. Installation was straightforward with standard tools.

5 FAQ

Q: What is the maximum operating speed (RPM)?

A: Due to the balanced brass construction, this coupling can safely operate at speeds up to 10,000 RPM, depending on the specific shaft diameter and application load.

Q: Is this coupling suitable for outdoor use?

A: Yes, the high-grade brass construction offers excellent corrosion resistance, making it suitable for outdoor or humid environments where steel might rust.

Q: Does it require special lubrication?

A: No special lubrication is required for the coupling itself. However, we recommend applying a small amount of anti-seize compound to the shafts before installation to facilitate future removal.

Q: What shaft diameters does this coupling support?

A: This model is available in various bore sizes ranging from 4mm to 20mm. Please select the specific size combination required for your motor and load shafts from the dropdown menu.

Q: Can this handle angular misalignment?

A: While primarily a rigid coupling, the elastic design elements allow for very minor angular misalignment (typically up to 0.5 degrees). For larger misalignments, a flexible bellows coupling is recommended.
