The lockable gas spring can be widely used in the office equipment, vehicles, mechanical equipment, medical facilities, height-adjustment chairs and tables and the like. Achieve the functions of automatic lifting, suspending, closing and the like. Its lifting force is basically constant during the whole working stroke. It has the cushion property, thereby avoiding the impact when objects are closed, and its moving stroke can be stayed at any places. When in operation, it requires no outside motive power, thereby saving the energy. It has the advantages of simple structure, small shape, convenient and quick installation and no need of maintenance.

The elastic locking gas spring has a buffering effect when the needle valve is released during the operation of the gas spring to open the needle valve, while the rigid locking gas spring has almost no buffering.

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)+ 18( Length of the piston rod's thread)

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

  • 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


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
