---

### **Cons**

1. **Limited Stroke Length**

- The **50mm stroke** is relatively short, making it unsuitable for **large displacement applications**.

- For longer strokes, a **larger model (e.g., NCQ40 or NCQ63 series)** would be required.

2. **Dependence on Compressed Air Supply**

- Requires a **reliable air compressor and filtration system** to prevent contamination or pressure drops.

- **Power outages or air supply failures** can halt operations unless backup systems are in place.

3. **Lower Force Output Compared to Hydraulics**

- Pneumatic systems generally provide **less force per unit area** than hydraulics, limiting use in **ultra-high-load applications**.

- May require **multiple cylinders** for heavy-duty tasks.

4. **Noise & Vibration**

- Pneumatic actuators can generate **audible noise and vibration**, which may require **soundproofing or damping solutions** in sensitive environments.

- Not ideal for **precision applications requiring ultra-quiet operation**.

5. **Temperature Sensitivity**

- While the **water-cooled version helps**, extreme temperatures (very hot or cold) can still affect **air viscosity and performance**.

- May require **environmental conditioning** in extreme climates.

6. **Higher Initial Cost for Advanced Features**

- Adding **water cooling, sensors, or smart controls** increases the **upfront cost**.

- May be **overkill for simple, low-demand applications**.

7. **Leakage Risks**

- Poor maintenance or damaged seals can lead to **air leaks**, reducing efficiency and increasing operational costs.
