Force vs. Stroke Overview
Understanding force and stroke is key to choosing the right gas strut. GASTAC provides clear guidance matching gas struts to different lid weights and sizes. Lower forces suit small cabinets, medium forces handle RV windows and toolboxes, and higher forces support heavy boat hatches or industrial panels. This ensures smooth, safe, and reliable motion in all applications.
| Force (N) | Recommended Applications |
| 50–200 | Small cabinets, lightweight lids |
| 200–400 | Toolboxes, RV windows, medium cabinets |
| 400–700 | Boat hatches, dock boxes, medium-heavy lids |
| 700–1200 | Heavy doors, industrial panels |
| 1200–2500 | Large industrial doors, medical equipment |
How to Choose Right Gas Springs Size ?
To choose the right gas spring, consider extended length, stroke, rod and tube diameters, and end fittings. Ensure the force matches lid weight and application. Correct sizing guarantees smooth motion, safety, and durability. GASTAC offers customizable options for marine, food-safe, and medical environments.
GASTAC Stainless Steel Gas Struts Installation Guide
Always mount gas springs with the rod pointing down to keep seals lubricated. Measure hinge positions and lid angles before drilling. Use strong stainless steel brackets and securely attach struts to ball sockets. Test the lid’s motion, and for adjustable models, fine-tune the force using the bleed valve for smooth, reliable operation.
