Gas Spring Series Selection Guide
13+ gas spring series serve different size, force, and feature requirements. Follow this decision tree:
| Series | Body Diameter | Key Feature | Best For |
|---|---|---|---|
| GSV | Ø24–Ø63 | Global Standard, broadest range | New die designs, general-purpose (recommended starting point) |
| GSK | Ø24–Ø50 | ISO 11901 compliant | International standard tooling, cross-manufacturer interchangeability |
| GSSC | Ø24–Ø50 | High initial load | Heavy blanking, deep drawing, maximum force at pre-load |
| GSU | Ø24–Ø50 | Adjustable charging pressure | Variable force requirements, fine-tuning without spring body change |
| GST | Ø24–Ø50 | Deeper mounting holes | Extra bolt engagement for high-vibration applications |
| GSH | Ø24–Ø50 | G 1/8 port for external gauge | Pressure monitoring, predictive maintenance |
| GSX | Ø24–Ø63 | Classic (original) type | Existing tooling replacement, legacy die compatibility |
| GSP | Compact | Compact high load | Maximum force-to-size ratio for space-constrained dies |
| GSN | Standard | Short type | Short stroke applications, minimal die height consumption |
| GSQ | Ø32 | Body Ø32, heavy load | Ø32 bore dies needing maximum force in this diameter |
| MGSL | Ø10–Ø16 | Mini type | Compact progressive dies, tight spaces |
| MGSN | Ø10–Ø16 | Mini heavy load | Compact dies needing higher force than MGSL |
| MGSM | Ø10–Ø16 | Threaded body | Direct insertion into threaded bores, no mounting plate needed |
Mounting Hardware Selection
| Criteria | Bottom Mount Plate | Lower Groove Mount | Upper Groove Mount | Horizontal Plate | Multi-Type |
|---|---|---|---|---|---|
| Installation | Vertical (bottom bolts) | Bottom (groove clip) | Top (groove clip) | Horizontal | Universal |
| Access for maintenance | Easy (open bottom) | Moderate | Moderate | Restricted | Flexible |
| Spring removal | Unbolt from bottom | Tool-free (slide out) | Tool-free (slide out) | Unbolt plate | Multiple options |
| Best for | Standard vertical dies (most common) | Quick-change dies | Top-access dies | Cam units, side-acting | Multi-series, mixed dies |
Default choice: Bottom mount plates are the most common mounting method. Switch to groove-mount brackets for quick-change die environments. Use horizontal plates only for cam and side-acting force applications. For detailed mounting guidance, see our How to Select Mounting Hardware for Nitrogen Gas Springs.
