| Stroke Length | 50 mm | Ideal for precise positioning tasks |
| Piston Action | Double-Acting | Provides controlled movement in both directions |
| Port Size | M5x0.8 | Standard metric thread for air connections |
| Proof Pressure | +1.05 MPa (150 PSI) | Maximum operating pressure rating |
| Construction | Aluminum Alloy | Lightweight yet durable material |
| Guide Type | Built-in Rail | Integrated guidance system |
| Mounting Style | Standard/Symmetric | Flexible installation options |
| Load Capacity | Approx. 15-20 N | Typical for 12mm bore guided cylinders |
| Operating Temperature | -10°C to 60°C | Suitable for most industrial environments |
The double-acting design ensures consistent performance in both extension and retraction cycles, while the integrated guide rail provides exceptional stability that's crucial for precision applications in packaging machinery and assembly lines.
Buying Considerations: Selection Guide
When selecting the SMC MXQ12L-50 or similar guided cylinders, consider these critical factors:
- Load Requirements: Calculate your exact load mass, including acceleration forces. The 12mm bore provides approximately 113 N of theoretical force at 0.7 MPa (100 PSI). Always apply a safety factor of 1.5-2x for dynamic applications.
- Stroke Length: The 50mm stroke is ideal for precise positioning tasks. For longer movements, consider larger MXQ models with up to 200mm strokes available in the series.
- Mounting Configuration: The MXQ12L-50 offers symmetric mounting options. Ensure your machine design accommodates the cylinder's footprint and mounting pattern.
- Speed Requirements: With proper pneumatic valves and flow controls, this cylinder can achieve precise speed control for delicate operations.
- Environmental Conditions: While rated for standard industrial environments, consider additional protection for harsh conditions with dust, moisture, or chemicals.
- Accessory Compatibility: Verify compatibility with your existing pneumatic fittings, sensors, and mounting hardware.
For applications requiring different specifications, explore the complete SMC MXQ Series with bore sizes from 6mm to 25mm and various stroke lengths.
Frequently Asked Questions
Q1: What is the maximum load capacity for the MXQ12L-50?
The MXQ12L-50 typically handles 15-20 N of dynamic load. However, actual capacity depends on mounting orientation, speed, and acceleration. For vertical applications, consider the weight of the load plus acceleration forces. Always consult SMC's technical documentation for specific application calculations.
Q2: Can this cylinder be used with position sensors?
Yes, the MXQ series is compatible with various sensing options. While this specific model doesn't include built-in sensors, you can add external cylinder position sensors or use the cylinder with proximity switches for position feedback in automated systems.
Q3: What maintenance is required for long-term reliability?
The MXQ12L-50 requires minimal maintenance: regular lubrication of the guide rails (if specified), periodic inspection for wear, and ensuring clean, dry compressed air supply. Use proper FRL units (Filter-Regulator-Lubricator) to extend cylinder life. Check mounting bolts periodically for proper torque to maintain alignment accuracy.
