Extension Springs/Tension Spring

Extension Springs/Tension Spring

An extension spring is a helical spring that elongates under tensile load and returns to its original shape when the load is removed. It is typically made of spring steel wire and designed with hooks or loops at both ends for fastening or connecting components.

Working Principle: When an external force pulls the two ends apart, the spring extends and stores energy; once the force is released, the spring contracts back to its original length.

Initial Tension: During manufacturing, a certain amount of preload is set so that the spring remains tightly coiled even without external force.

Connection Options:d according to specific application requirements.
