    1. Swift and Sure Gas SpringA damping device is installed to its stroke terminals for the sake of safeguarding components and operators.
      Products of different sizes are available to meet various application requirements. This range of non-lockable gas spring is easy to install.
    1. Stop and Stay Gas SpringIt is freely locked. With this friction stop gas spring, doors and covered can be opened to specific positions.
      Though simple in structure, it offers the most cost-effective solutions.
    1. Safety Locking Shroud Gas SpringThe industrial gas strut is meticulously designed. Its protection shroud is securely fixed onto a rod, which won't affect its normal operation. Additionally, the low additional cost of product materials decreases the purchase cost.
    1. Gas Spring with Dynamic Damping As compared to standard gas struts, the damped gas spring has an additional core spring on its tube bottom. The core spring has damping effect to movement. Inside the tube, there is a special groove.
    1. Telescopic Gas Spring The non locking gas spring can maximally stretches to 400mm. That means it lets you open a door or lid to a larger space than a general spring does. Besides that, it can be used to lift objects to a required height.
    1. Adjustable Force Gas SpringThrough the adjustment, the non-locking gas spring can reach to the desired position. A standard variable force gas strut could be one-way or two-way force adjusted.
    1. Traction Gas SpringThe non locking gas spring is suitable for the industries including cars, trucks, agricultural machinery, medical equipment, office furniture, printing machinery, among others.

Non-Locking Gas Spring

A non-locking gas spring is a gas strut ideally suited to all applications where loads are required to be lifted or lowered in a controlled way. It is used to provide auxiliary force for realizing optimum weight equalization, which will make doors and lids easily opened or closed. Its damping force characteristic is conducive to safe motion sequences and user-friendly operation.

1. Boxi non-locking gas spring comes with a wide range of sizes, terminal fittings, and force ranges.
2. Featured by flat spring curve, it works stably even when working under high forces or large strokes.
3. The non-locking gas spring is convenient in installation, safe in use, simple in structure. It occupies less space.
4. Upon request, it can be designed to be with variable locking mechanism. Also, additional functions including electric switches, stop function, end position lock, etc., can be integrated.
5. This product is maintenance-free. It can be used for at least 30,000 times.

Classifications and Application of Non-Locking Gas Spring
Based on its purpose, the non-locking gas strut is classified into the compression gas spring and the traction gas spring.
1. A compression gas spring is commonly used for supporting purpose in industries such as automotive, construction equipment, medical equipment, among others.
2. Unlike the former, the traction gas spring retract rather than extend during operation. It is chiefly applied to doors and windows as well as fitness equipment.

Construction and Working Principle
Boxi non-locking gas spring is extremely stable in structure. When using, piston rod of this non-lockable gas spring is installed downward. While the piston rod is being pressed into the steel cylinder, oil automatically flows from the steel cylinder into the cylinder cavity with rod. Under the function of differential pressure between two piston ends, piston rod will be forced out. Oil inside the cylinder cavity has such functions as cushioning and lubrication.
