Custom Stainless Steel Long Tension Coil Springs For Furniture
Extension Spring, also known as spiral stretching spring, is generally equal pitch, the cross-section is round, they can be used in many occasions, such as production and assembly, experiment, research and development, maintenance, etc.. Tension springs occupy an important position in the global market, widely used in national defense, Marine, computer, electronics, automobile, mold, medicine, biochemistry, aerospace, railway, nuclear power, wind power, thermal power, construction machinery, mining machinery, construction machinery, elevator and other fields.

1. What is a tension spring?
A: Tension springs are wound helical coils that are wrapped tightly
together to create tension. Also called extension springs, tension
springs provide extended force when the spring is pulled apart from
its original length.
2. What is the difference between a compression spring and a
tension spring?
A: Although a tension and compression spring are both helical coiled
springs, the difference in their functionality and purpose can be
significant. In essence, tension springs are designed to bring
components together, whilst compression springs are made to keep
components apart.
3. What is the formula for tension of a spring?
A: F = -kx. The proportional constant k is called the spring
constant. It is a measure of the spring's stiffness. When a spring
is stretched or compressed, so that its length changes by an amount
x from its equilibrium length, then it exerts a force F = -kx in a
direction.
4. Is tension a spring force?
A: Tension denotes the energy stored in the spring (assuming it is a
tension spring). Spring force is release and utilization of this
energy for a specific purpose.n towards its equilibrium position.
5. What is a tension spring on a sewing machine?
A: The bobbin or lower tension, as it is sometimes referred to, is
adjusted by tightening a screw against a flat spring and the
spring, in turn, pinches the thread leaving the bobbin creating the
tension needed to manage the loops and balance the stitch.
