Reliable industrial component

Been running this on a continuous duty cycle for three months now with no signs of wear. The gear teeth engagement is smooth. Great value for the price compared to branded alternatives.

Great replacement part

Our old coupling cracked, and this was the perfect direct replacement. The curved tooth design seems to distribute load evenly. No overheating issues observed so far.

Perfect fit for our hydraulic pump

We replaced a metal coupling with this nylon sleeve version to reduce noise and vibration. It fits perfectly on our oil pump motor setup. The curved teeth design handles minor misalignments very well.

Good quality, fast shipping

The build quality is solid. The nylon feels durable and not brittle. Installation was straightforward using the provided set screws. Deducting one star only because the instructions were a bit vague, but standard knowledge applies.

Works as described

Bought this for a retrofit project. The dimensions matched our specs exactly. It handles the torque requirements without slipping. Would buy again if we need more units.

Excellent vibration damping

This coupling significantly reduced the humming noise in our machinery. The flexible nylon sleeve absorbs shocks better than the rigid coupler we had before. Highly recommended for motor connections.

5 FAQ

Q: Can this be used in outdoor environments?

A: Yes, the nylon material is resistant to weathering. However, for prolonged exposure to direct UV sunlight or harsh chemicals, we recommend checking the specific chemical resistance chart or using a protective cover.

Q: Does this coupling require lubrication?

A: No, the NL Nylon Sleeve Gear-Type Coupling is self-lubricating due to the nylon material properties. Adding external grease is not recommended as it may attract dust.

Q: How do I install the sleeve onto the hubs?

A: Align the curved teeth of the two hubs with the internal grooves of the nylon sleeve. Slide the sleeve over one hub, align the second hub, and then slide the sleeve to cover both sets of teeth evenly. Ensure full engagement before tightening set screws.

Q: What is the maximum bore size this model supports?

A: For model NL23456789, the maximum shaft diameter (bore) it supports is 45mm. Please ensure your shaft falls within the 20mm to 45mm range for optimal performance.

Q: Are the set screws included metric or imperial?

A: The set screws included in the package are Metric (M6). If you require imperial adapters, please contact us separately.
