Solid construction, good value

The 45# steel feels very robust. The nylon insert provides just enough flexibility to absorb minor misalignments between the motor and pump shafts. Only giving 4 stars because shipping took a bit longer than expected.

Good quality, check your specs

Quality is top-notch. Just make sure to double-check your shaft diameters before ordering, as the fit needs to be exact. Once installed correctly, it works flawlessly.

Reliable for continuous operation

Our facility runs 24/7, and these couplings have held up perfectly under constant load. No signs of wear on the nylon sleeve after three months of operation. Highly recommended for industrial use.

Perfect fit for our hydraulic pumps

We replaced several worn-out couplings with this NL Nylon Sleeve model. The fit was precise, and the high torque capacity handles our heavy-duty oil pumps without any slippage. Installation was straightforward.

Excellent vibration damping

Since installing these couplings, the noise level in our machinery room has dropped significantly. The internal gear design effectively dampens vibrations while transmitting power efficiently.

Best replacement part we found

We struggled to find a durable replacement for our older pump systems until we found this. The combination of steel and nylon offers the perfect balance of strength and flexibility.

5 FAQ

Q: Can this be used in outdoor environments?

A: Yes, the 45# steel components feature a black oxide coating that provides corrosion resistance. However, for harsh chemical or marine environments, additional protective measures may be advisable.

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

A: Yes, the nylon internal gear sleeve is designed to be replaceable. You do not need to replace the entire steel hub assembly, which reduces long-term maintenance costs.

Q: Does this coupling require regular lubrication?

A: No, the NL Nylon Sleeve design is self-lubricating due to the high-quality nylon insert, making it virtually maintenance-free under normal operating conditions.

Q: What is the maximum angular misalignment this can handle?

A: This coupling can typically compensate for angular misalignments up to 1.5 degrees, depending on the specific size and load conditions. Please refer to the technical datasheet for exact figures per model size.

Q: What sizes are available for this product line?

A: We offer a wide range of sizes to fit various motor and pump shaft diameters. Please contact our sales team with your specific shaft dimensions so we can recommend the correct model number.
