Gas spring model marking method

Gas spring type marking method ※ The gas spring mark is composed of 1 code, 2 piston rod diameter, 3 cylinder outer diameter, 4 strokes, 5 extension length, 6 rod end fittings and cylinder end fitting form, and 7 minimum extension force . The regulations are as follows:
×××××/××-×××-××× (××-××) ×××
1 2 3 4 5 6 7
※ Various types of gas springs: Compressed gas spring (YQ), Liftable lockable gas spring (SKQ), Angle adjustable lockable gas spring (JKQ), Balanced gas spring (PQ), Stretch gas spring (LQ), Damper (ZQ)
※ The piston rod diameter, cylinder outer diameter, stroke, and extension length are in millimeters (mm), and the minimum extension force is in Newtons (N).
※ Connector type code: single piece (O), binaural (U), monaural (L), ball hinge (B), thread (M), taper (S)
※ Marking example: The diameter of the piston rod of the compressed gas spring is 10mm, the outer diameter of the cylinder is 22mm, the stroke is 260mm, the extension length is 630mm, the piston rod end joint is monolithic, the cylinder end joint is ball joint type, the minimum extension The force is 380N.
