Purchase now: Wittenstein NP015S-MF1-10-1C1-1S Gearbox
Purchase now: Atlantech Drives provides you the Wittenstein Alpha NP015S-MF1-10-1C1-1S, a state-of-the-art **Planetary Gearbox** from the **NP Series**. This unit offers a reduction ratio of **10:1**, which is particularly useful for **Inertia Matching**. By reducing the reflected load inertia by a factor of 100 (ratio squared), it allows a small servo motor to control a relatively large load with high dynamic response and stability. The NP series offers significantly improved torque ratings over the older CP series.
Technical Specifications and Interface 1C1
The defining feature of this SKU is the **»-1C1″ Input Interface**. This code ensures compatibility with a specific motor geometry. Whether you are using a Siemens, Rockwell, Yaskawa, or Bosch Rexroth motor, you must confirm that its shaft and flange dimensions align with the Wittenstein «C» interface specifications for Size 015. Using the correct interface ensures perfect concentricity, extending the life of the input bearings and preventing vibration.

Expert Maintenance: Thermal Derating
Small but hot. Expert Tip: The Size 015 is a small gearbox. When running at high speeds (e.g., 4000 RPM input), it generates heat. If the ambient temperature is high (> 30°C), you may need to derate the torque or duty cycle to prevent the internal grease from degrading. Always ensure adequate airflow around the motor/gearbox assembly.
Frequently Asked Questions (FAQs)
Q: Does this gearbox need oil changes?
A: No. The NP015S is lubricated for life with a specific high-performance grease. It is sealed and requires no maintenance during its service life.
Q: What is the «1S» suffix?
A: It refers to the **Smooth Output Shaft**. Wittenstein recommends smooth shafts for servo applications to avoid the backlash inherent in keyed connections. Use a clamping coupling for the output load.
