Gas Springs

A gas spring – also called a gas strut, gas lift or tailgate strut – uses nitrogen compressed in a sealed cylinder to support, cushion and position loads on tailgates, office chairs, hospital beds and lift-up doors. This section covers gas spring structure, working principle, types, selection and applications, and how a gas spring cylinder is produced from tube to finished part.

TONG DA Precision (Tainan, Taiwan, since 1989) builds machines for gas spring cylinders: tube closing, inner grooving, oil filling, press-fit & edge folding and lock nut machines. For quotations, email sales@tdco.com.tw.
