Tension Spring

Extension springs are usually installed in situations where axial tension is required to provide support and resilience. For example, in car doors, furniture, musical instruments and safety equipment, extension springs help support weight, reduce wear, provide comfort and extend service life. In power tools, extension springs are used to provide tensile support to ensure the normal operation of the tool. In guitars, extension springs are used in tremolo systems to adjust the angle of the bridge, affecting the tone and intonation stability.
