Excellent vibration damping

Used this to connect a 5HP motor to a hydraulic pump. The elastic torque coupling absorbs shocks effectively, reducing noise levels significantly. Highly recommended for heavy-duty applications.

Durable but slightly pricey

The SS304 material gives me peace of mind regarding rust in our humid workshop. Installation was straightforward. Only giving 4 stars because it costs a bit more than aluminum alternatives, but worth it for longevity.

Perfect fit for our air compressor

We replaced an old rubber coupling with this stainless steel version on our industrial air compressor. The build quality is exceptional, and it handles the vibration much better than the previous unit.

Solid construction

The machining on the hubs is precise, ensuring a tight fit on the shafts. It has been running for three months without any issues. Would have given 5 stars if it came with a spare spider insert.

Great replacement part

Exactly what I needed for my CNC machine retrofit. The jaw type design allows for easy replacement of the spider insert without moving the connected shafts. Very satisfied with the purchase.

5 FAQ

Q: How do I align the motor and pump shafts before installing?

A: We recommend using a laser alignment tool or dial indicators to ensure angular and parallel misalignment is within the specified limits (usually <0.5mm) before tightening the set screws.

Q: Can this be used in outdoor applications exposed to rain?

A: Absolutely. Since it is made from Stainless Steel 304, it offers excellent resistance to rust and corrosion, making it suitable for outdoor and wet environments.

Q: Is lubrication required for the jaw mechanism?

A: No, this is a maintenance-free coupling. The elastomeric spider element operates without grease or oil, which prevents contamination in clean environments.

Q: Does this coupling come with the orange polyurethane spider insert included?

A: Yes, the package includes one high-quality polyurethane spider insert pre-installed or packed alongside the hubs.

Q: What is the maximum bore size available for the XL3 model?

A: The XL3 model typically supports bore sizes up to 45mm, but please check the specific technical drawing for your required tolerance and keyway dimensions.
