NL Gear Nylon Sleeve Coupling Is Used For Water Pumps, Fans And Reducers

According to the mechanical industry standard JB/T 5514-2022, its rated torque range is usually from 10 N·m to 8000 N·m, and it is suitable for working conditions with a rotational speed not exceeding 4000 rpm. Compared with all-metal couplings, the flexible design of nylon internal teeth can reduce the vibration and noise of the transmission system, decrease the frequency of maintenance and extend the service life of the equipment. It is commonly used in equipment such as water pumps, fans and reducers, and performs particularly well in damp and dusty environments.

1. Super load-bearing capacity

The upper limit of torque transmission is 8000Nm‌, and the impact resistance is enhanced by 40%.

2. Long-lasting wear resistance ‌

The wear rate of the self-lubricating nylon gear sleeve is ≤0.1mm per thousand hours, and its service life is over ‌ 30,000 hours ‌.

3. Precise compensation

Compensate for ‌ radial deviation ≤1.1mm‌ + ‌ angular deviation ≤1°‌ axial deviation ±1mm‌, reducing installation alignment cost by 50%.

4. Zero-maintenance operation

The dry meshing structure requires no lubrication for life, with an IP55 protection rating (dust spray resistance/low-pressure water resistance), making it suitable for highly polluted environments such as mines and ports.

5. Low cost ‌

Only the nylon gear sleeve needs to be replaced after wear, and the metal parts ‌ are 100% reused ‌, reducing maintenance costs by 60% directly.

6. Vibration suppression

The backlash preloading design absorbs ‌≥15% of the vibration energy of the ‌ equipment, protecting the bearings/gearboxes and extending the service life of downstream equipment.

7. Extreme working condition adaptation

 stable operation throughout the full temperature range from -40℃ to +120℃ (nylon resistant to brittle cracking at low temperatures and creep at high temperatures), with a humidity tolerance of 100%.
