Q1. What is mechanical lock (spring stopper adjuster)? Is this same as the gas spring?

A1. It is a linear actuator which comprises the locking springs, the rod, outer tube, actuator lever and the attached ends. You can use mechanical lock to lock the stroke rigidly in any position. Mechanical lock doesn’t have air and oil leakage issues compared to gas spring. It can be applied to anywhere you want to adjust the linear position without any bouncing force (a gas spring commom problem).

Q2. What is gas spring stopper?

A2. It combines gas spring and mechanical lock. It has not only the strong thrusting force like gas spring but also rigid locking when exact position is necessary. Gas spring stopper makes a rigid mechanical locking connection with thrust force from gas spring.

Q3. What is the difference between mechanical lock and gas spring stopper?

A3. The gas spring stopper is much longer than the mechanical lock since it combines two parts (gas spring & mechanical lock) together. The gas spring stopper can be applied to the function which requires a force to lift an upwards opening or any loads. The mechanical lock can minimize the length much shorter than the gas spring stopper. It can be applied to the function which needs no force or thrust while locking the stroke rigidly in any position.

Q4. What is the difference between gas spring stopper and lockable gas spring?

A4. Both provide thrust forces to lift loads smoothly and effortlessly. However, lockable gas spring will fail if it wears resulting in air leakage. Our Gas Spring Stopper can still have the locking function controlled by the mechanical lock even when small quantities of air may leak as a sign of wear after lengthy periods of use.

Q5. Can you offer some standard products as samples?

A5. All of our products are customized and the design is based on what our customers want to apply to. So we don’t have any standard product because the dimensions differ from every single demand. You can provide the information about the applications and your design to us, then we can offer you the samples for review.
