Advantages of Friction Springs

1．Large load, light weight, small size

2．The characteristic curve can be changed by selecting the number of rings

3．Linear characteristic curve

4．Overload protection feature when pressing and closing position

5．High damping capacity

6．The characteristic curve appears repeatedly with the compression return stroke, and the attenuation is small.

7．Easy maintenance, long life

8．Friction springs can be arranged in parallel with several spring groups of different specifications to achieve greater force, or arranged in series to achieve greater spring travel

9．Made of durable spring steel, friction springs can also withstand fire and heat that can destroy rubber products. In the event of a fire, simply re-lubricate the spring and it will be ready for use
