Reliable industrial component

We ordered several units for our production line in Dongguan. Consistency across all units was impressive. No vibration issues since installation.

Excellent torsional stiffness

I needed a coupling that could handle high torque without flexing too much. This diaphragm coupling delivers perfect performance for my servo application.

Good but check dimensions carefully

The product is high quality, but make sure you measure your shaft diameter accurately before ordering. The keyway size matched my specs perfectly though.

Great value, fast shipping

Works exactly as described on my stepper motor project. The double diaphragm design handles minor misalignments very well. Only giving 4 stars because the instructions were minimal.

Perfect fit for my CNC setup

The build quality is exceptional. The aluminum alloy feels robust yet lightweight, and the keyway fit was precise with no backlash. Highly recommended for precision motion control.

Smooth operation

Installed this on a lead screw drive and the movement is incredibly smooth. The anodized finish also looks professional and resists corrosion.

5 FAQ

Q: How do I install this on a lead screw?

A: Align the motor and lead screw, insert the coupling, tighten the set screws evenly using a torque wrench, and ensure the keyway is fully seated before operation.

Q: Is the keyway standard metric or imperial?

A: Our standard stock items use metric keyways, but we can manufacture imperial keyway versions upon request for bulk orders.

Q: What is the maximum RPM rating for the single diaphragm version?

A: The single diaphragm version is rated for up to 4,000 RPM depending on the specific size and load conditions. Refer to the technical datasheet for detailed charts.

Q: Can this be used in a vacuum environment?

A: While the aluminum alloy is suitable, the standard lubricants may not be vacuum-compatible. Please consult our engineering team for specialized vacuum-grade options.

Q: Does this coupling come in different bore sizes?

A: Yes, we offer a wide range of bore sizes to fit various motor shafts. Please check the specific variant options or contact us for custom sizing.
