Durable and Reliable
We use these for multiple fan units. They have been running for 6 months without any wear on the spider insert. Highly recommend for high-torque apps.

Reduced Noise Significantly
Replaced an old rigid coupling with this elastic jaw type. The noise reduction in the pump room is noticeable. Very happy with the purchase.

Perfect for Air Compressor
Installed this on my industrial air compressor setup. The alignment was off slightly, but this coupling absorbed the vibration perfectly. Solid steel construction.

Good Quality, Tight Fit
The material quality is excellent. The keyway was a bit tight and required some filing, but overall it holds torque well without slipping.
Q: What is the maximum operating temperature for this unit?
A: The standard elastic insert is rated for continuous operation up to 80°C (176°F).
Q: Is this suitable for underwater pump applications?
A: The steel has a black oxide coating, but for submerged applications, we recommend additional corrosion protection or stainless steel variants.
Q: Can the bore size be re-machined if needed?
A: Yes, 45# steel can be re-bored within reasonable limits, but please consult a machinist to maintain structural integrity.
Q: Does this coupling come with the elastic spider insert?
A: Yes, the package includes the coupling hubs and the appropriate elastic spider insert.
Q: How much axial misalignment can this tolerate?
A: This XL series coupling can tolerate axial misalignment up to 2mm while maintaining performance.
