Durable and reliable

Been running these in a high-cycle environment for three months now. The elastic spider element shows no signs of wear, and the aluminum hubs remain tight. Great value for heavy-duty applications.

Excellent vibration damping

The star-type design really helps dampen shock loads in our system. We noticed a significant reduction in noise levels immediately after installation. Highly recommended for pump motors.

Fast shipping and robust build

Arrived earlier than expected. The build quality feels very robust, much heavier than the previous brand we were using. The anodized finish looks like it will hold up well against moisture.

Good quality, check bore specs

The coupling itself is excellent quality. Just make sure to specify your exact bore size when ordering, as it comes un-bored by default. Once machined to fit, it works flawlessly.

Perfect fit for our industrial pumps

We replaced several worn-out couplings on our water treatment facility pumps with this XL model. The torque handling is impressive, and the installation was straightforward. No vibration issues since the swap.

Solid performer

Does exactly what it says on the tin. High torque capacity without the bulk. Took off one star only because the instruction diagram could be clearer, but standard installation practices apply.

5 FAQ

Q: How does this compare to a rigid coupling for water pumps?

A: Unlike rigid couplings, this elastic jaw coupling compensates for angular, parallel, and axial misalignments while damping torsional vibrations, which significantly extends the life of pump bearings and seals.

Q: Can this coupling handle underwater submersion?

A: While the aluminum hubs are anodized for corrosion resistance, this coupling is designed for drive trains, not for permanent submersion. It is suitable for splash zones and humid environments typical of pump rooms.

Q: What is the maximum operating temperature for the standard green spider?

A: The standard polyurethane spider (92 Shore A) is rated for continuous operation between -30°C and +80°C. For higher temperatures, we offer alternative materials upon request.

Q: Do you provide custom boring services for specific shaft diameters?

A: Yes, we offer precision boring and keyway cutting services. Please contact our sales team with your shaft diameter and tolerance requirements before placing your order.

Q: Is the spider element replaceable without removing the hubs?

A: Yes, one of the main advantages of the ROTEX star-type design is that the elastic spider can be replaced radially without needing to move the connected shafts or remove the hubs.
