Buying Considerations: Selection Guide for Three-rod Guide Cylinders
When selecting the SMC MGPL16-20Z or similar three-rod cylinders, consider these critical factors:
- Bore Size Selection: The 16mm bore provides approximately 20N of force at 0.5 MPa. Calculate required force based on your application's load and acceleration requirements.
- Stroke Length Requirements: The 20mm stroke is ideal for short, precise movements. For longer strokes, consider alternative models in the MGPL series.
- Load Capacity Analysis: Evaluate both axial and lateral loads. The three-rod design excels at resisting side loads up to 30N.
- Mounting Configuration: Front flange mounting simplifies installation. Ensure your mounting surface provides adequate rigidity.
- Environmental Conditions: Verify temperature range compatibility and consider additional protection for harsh environments.
- Speed Requirements: Adjustable cushions allow fine-tuning of end-of-stroke speed for optimal cycle times.

Frequently Asked Questions
Q1: What makes three-rod guide cylinders different from standard cylinders?
Three-rod guide cylinders feature three precision-ground rods arranged in a triangular configuration, providing superior resistance to rotational forces and side loads. Unlike single-rod cylinders that can rotate under load, this design maintains precise linear alignment, making them ideal for applications requiring exact positional accuracy.
Q2: How do I calculate the force output of the MGPL16-20Z?
Force calculation follows standard pneumatic principles: Force (N) = Pressure (MPa) × Bore Area (mm²) × 10. For the 16mm bore: Area = π × (8mm)² ≈ 201 mm². At 0.5 MPa operating pressure: Force ≈ 0.5 × 201 × 10 = 1005N (approximately 100N). Remember to account for efficiency losses (typically 80-90% for pneumatic cylinders).
Q3: Can the MGPL16-20Z be used in vertical applications?
Yes, the MGPL16-20Z can be used in vertical orientations, but additional considerations are necessary. The three-rod design provides excellent stability, but you must account for gravity effects on the load. For vertical applications, ensure proper sizing to handle the combined weight and acceleration forces, and consider using counterbalance valves for controlled descent.
