​ Which Locking Gas Spring Type Should You Choose?

As a professional gas spring manufacturer, Gastac Gas Spring provides locking gas springs for different load directions, comfort requirements, and safety needs.

Elastic Locking Gas Spring 1

Elastic Locking Gas Spring

Elastic locking gas springs are a good choice when a slight rebound in the locked position is required. This design helps absorb sudden peak loads and can reduce or prevent impact forces.

Typical applications include:

  • Backrest adjustment for seats
  • Height adjustment of medical equipment
  • Armrest adjustment
Rigid Locking Gas Strut in Extended Direction 1

Rigid Locking Gas Strut in Extended Direction

Rigid locking in the extension direction is recommended when any rebound after locking must be avoided, especially in applications where safety and stable positioning are critical.

Typical applications include:

  • Backrest adjustment for seats
  • Tilt adjustment of hospital beds
  • Leg supports for wheelchairs and passenger seats
Rigid Lockable Gas Spring in Compressed Direction 1 1

Rigid Lockable Gas Spring in Compressed Direction

 

Rigid locking in the compression direction is recommended for light-duty applications that may be exposed to very high forces after locking, where any further compression must be prevented.

Typical applications include:

  • Tilt adjustment of massage, treatment, and transport beds, including stretchers
  • Tilt adjustment of steering columns in construction and agricultural machinery
  • Height adjustment of hospital bedside tables, overbed tables, and server tables
  • Height adjustment of bistro tables, desks, and coffee tables

Locking Gas Spring Specifications

When selecting or replacing a gas spring, it is important to measure the key dimensions accurately. Start with the Rod Diameter and Body Diameter, which determine the strength and load capacity of the gas spring. Next, measure the Stroke, which is the distance the rod can travel between the fully compressed and fully extended positions. Finally, record the Extended Length, which is the total length of the gas spring from the center of one end fitting to the other when fully extended. By following these steps, you can ensure the correct specifications for your application and achieve reliable performance.

Frequently Asked Questions

A locking gas spring is a gas spring that can hold a load securely in place at any position, preventing sudden drops or movement.

Gas strut safety lock features provide extra safety and precise control by holding loads at any position — ideal for heavy loads or safety-critical applications.

High-quality models, such as GASTAC, typically endure tens of thousands of cycles with stable and reliable performance under proper use.

Match the spring’s force to the weight of your load and desired ease of movement.

Install with the piston rod facing downward when possible. Use proper brackets, keep alignment, and avoid side loading.
