Custom Stainless steel Precision Cylindrical Coil Spring

There are many types of coil springs, which can be divided into general cylindrical spiral springs and variable diameter spiral springs according to their appearance. According to the direction of the helix, it can be divided into: left-handed spring and right-handed spring.


Cylindrical coil spring have simple structure, convenient manufacturing, and the most widely used. Its characteristic line is a straight line, which can be used as compression spring, extension spring and torsion spring. When the load is large and the radial size is limited, two compression springs with different diameters can be sleeved together to form a combined spring.

The coil spring has precise adjustment performance. That is, the relationship between force and displacement is very sensitive, with good softness, that is, the range of deformation is relatively wide, the manufacturing is relatively easy, the structure is relatively compact, and the energy rate is high.


Coil spring has the advantages of no need for lubrication, no fear of dirt, small weight and less space and position. It is often used as a balancing mechanism in machinery and is widely used in industrial production such as automobiles, machine tools, and electrical appliances.
