Description

The self-lock gas spring is one of the gas strut springs, which increases the locking device on the basis of the standard gas strut spring. When the gas spring is compressed to the shortest, it can be locked to maintain the compression state.

Dimension of Self-locking gas spring

F1 Force	Stroke	Surface treatment	Standard of product execution	Service life
50N-300N	30MM-350MM	tube painting, piston rod hard chromium plating\QPQ	GB/T 25751-2010	At least 28000 times

Calculation of tube length and stroke
L（ Total length of fully extended）= A（ tube length）+ S（ Stroke）+ 20（ Installation length on the piston rod's end）

Computational formula of tube length and stroke: A≥S+80.（ As the length of stroke increases, the length of tube will increase.)

Calculation of tube length and stroke

L（Total length of fully extended）=A（tube length）+S（Stroke）+13（Installation length on the tube's end）+13（Installation length on the piston rod's end）

Computational formula of tube length and stroke: A≥S+30.（As the length of stroke increases, the length of tube will increase.)

Advantage

Variable elastic locking and optimized weight compensation during lifting, lowering, opening and closing
Comfortable bouncing and damping of shocks, impacts, or sudden peak loads
Compact design for installation in tight spaces
Long life cycle, nearly 5000 times
Strict electrostatic coating line control quality.
More environments friendly with QPQ material and salt spary test more than 96 hours
Best materials and equipment for endings, available in screw thread or one-piece construction

Applications

Elastic locking gas springs are ideal for applications that require a certain level of comfort (cushion or elasticity).

Elastic locking in backrest adjustment of swivel chairs or massage chairs
Height adjustment of physician’s stools with foot actuation
Generally suited for elastic locking of elements where no additional loads need to be held besides the application load
