Excellent vibration damping

Since installing this NL coupling, the noise level from our motor setup has decreased significantly. The nylon sleeve does a fantastic job of absorbing vibrations. Highly recommended for noisy setups.

Perfect fit for our industrial pump

This coupling replaced an old worn-out part on our water pump system. The 45# steel feels very robust, and the nylon sleeve fits snugly without any play. Installation was straightforward thanks to the easy assembly design.

Easy maintenance

The design really shines when it comes to maintenance. We needed to inspect the shaft alignment recently, and taking this coupling apart was incredibly quick and easy. Will definitely buy again.

Good quality, fast shipping

The build quality is solid. We use these for several oil pumps in our facility. The only reason for 4 stars instead of 5 is that the instructions could be slightly more detailed, but overall a great product.

Durable and reliable

We have been running this coupling continuously for three months now under heavy load. No signs of wear on the gear teeth or the nylon sleeve. It handles the torque requirements perfectly.

Great value for money

For the price, you cannot beat the quality. It works just as well as more expensive brands we have tried in the past. The black oxide coating also seems to resist rust well in our humid environment.

5 FAQ

Q: Does this coupling come with the nylon sleeve pre-installed?

A: Yes, the NL coupling arrives with the nylon sleeve already fitted into the gear hubs, ready for immediate installation.

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

A: The 45# steel has a protective black oxide coating which offers some resistance, but for prolonged outdoor exposure to rain, we recommend adding an extra layer of protective grease or housing.

Q: What is the maximum RPM rating for this specific model?

A: While ratings vary by specific size, standard models in this series typically handle up to 3000 RPM. Please check the specific datasheet for your bore size.

Q: Do you offer bulk discounts for orders over 50 units?

A: Yes, we provide tiered pricing for bulk orders. Please contact our sales team directly through the 'Contact Seller' button for a custom quote.

Q: Is the nylon sleeve replaceable if it wears out?

A: Absolutely. One of the main advantages of the NL type is that the nylon sleeve is a separate component and can be easily replaced without discarding the metal hubs.
