=== Description ===
Two-way

In order to obtain the ideal damping effect when the chair seat rebounds, it is particularly important to select and make various styles of springs that match it while selecting our company's dampers suitable for torque.
 As shown below:
1. The thickness of the steel wire for making the spring is preferably 2.8~3.2 in diameter, and the rigidity should be 60Si2Mn the most suitable.2. The coil should not be less than 6 full turns, and the spacing between the coils should be 1.5-2mm.3. The length of the spring leg should not be less than 100mm, and the end of the spring leg should be bent at a length of 20mm by 30°, and the spring leg should be fastened to its support in a horizontal state during assembly.4. Since the strength of the torsion spring is proportional to the torsion angle during assembly, it is extremely important to choose different torsion angles that are suitable for the damper torque value according to the different structure and weight of the seat. The general spring torque angle is 90°~120°, adjusting the angle can change the elasticity and the seat turning speed, that is, 1/4 to 1/3 of a circle.
