Key features & benefits
- Safe, controlled motion: Internal damping for soft-open / soft-close; reduces rebound and noise.
- Right force, first time: Precisely charged to match door weight, hinge geometry, and desired opening angle.
- Durable in harsh environments: Black-nitrided piston rod or 316 stainless for corrosion resistance in coolant and wash-down areas.
- Clean installation: Compact cylinders, multiple end fittings, and adjustable brackets simplify retrofits.
- Maintenance-friendly: Long service intervals; easily replaceable with quick-release hardware.
- Compliance support: Helps meet machine guarding best practices by minimizing unexpected panel drop.
Typical specifications
- Stroke: 50–400 mm (2–16 in); Extended length: 180–900 mm
- Force range: 50–1200 N (11–270 lb); Progression tailored to application
- Materials: Carbon steel (black nitrided) or Stainless 316; oil- or grease-filled
- End fittings: Ball-socket, eyelet, fork/clevis, threaded stud; mounting L-/U-/flat brackets
- Options: Valve-adjustable force, slow-speed damping, food-grade lubricant, custom logos/part numbers
Which types are suitable
- Compression Gas Spring: The primary choice for lifting and holding guards/doors open with consistent support.
- Stainless Steel Gas Spring: For wet, corrosive, or wash-down zones around CNCs and packaging lines.
- Adjustable Locking Gas Spring (inter-stop): Allows positioning the guard at any angle; ideal for inspection hatches.
- Traction Gas Spring (tension): Assists in pull-down or counter-pull mechanisms on overhead access panels.
- Hydraulic Dampers: Add extra closing control to heavy panels or where ultra-quiet motion is required.
- Safety Locking Gas Spring: Integrated mechanical lock to prevent sudden drop during maintenance.
- Micro & Mini Gas Springs: For small service flaps, sensor covers, or lightweight polycarbonate windows.
Applications
CNC machine guards and operator doors: Gas struts / gas springs hold vertical sliding or side-hinged doors open, acting as reliable lift supports with tuned damping to prevent slam on shutdown.
Access panels on conveyors and fillers: Compact gas shocks fit within narrow frames, enabling quick tool-less access to belts, sensors, and nozzles while maintaining stable holding torque.
Electrical and servo enclosures: Gas props provide controlled opening for inspection windows, improving ergonomics in preventive maintenance routines.
Packaging and labeling line hoods: Pneumatic struts and nitrogen gas springs counterbalance acrylic or aluminum lids, reducing operator effort and hinge wear.
Selection guidance
Share panel weight, dimensions, hinge side, target open angle, and envelope constraints.
Land engineers simulate force curves and pick cylinder Ø / rod Ø / stroke for balance and hold-open.
Choose material (black-nitrided or SS316) and end fittings; confirm bracket geometry.
We ship pre-charged struts with installation torque and force-adjust notes where applicable.
