Compression springs are the most common type of springs and are widely used in many applications. These springs are designed to resist compression forces and provide resistance when compressed. They are typically made of round wire and have an open-coil helical shape. Compression springs are used in automotive suspensions, industrial machinery, consumer products, and more.
Tension Springs
Tension springs, also known as extension springs, work in the opposite way of compression springs. They are designed to resist stretching forces and provide resistance when extended. Tension springs are typically made of round wire and have a helical shape with hooks or loops at the ends. They are commonly used in garage doors, trampolines, balance scales, and various other applications that require pulling or stretching forces.
Torsion Springs
Torsion springs are designed to resist twisting or rotational forces. They store mechanical energy when twisted and release it when the torque is released. Torsion springs are commonly used in applications such as clothespins, mouse traps, door hinges, and various other devices that require rotational movement. They are typically made of round wire and have a helical shape with legs or arms at the ends.
Constant Force Springs
Constant force springs provide a constant amount of force throughout their deflection range. Unlike compression or tension springs, constant force springs exert the same force regardless of their extension or compression. These springs are commonly used in applications such as retractable tape measures, window blinds, and counterbalance systems. They are typically made of flat strip material and have a tightly wound coil shape.
Belleville Springs
Belleville springs, also known as disc springs or conical washers, are unique in their shape and function. They are conical-shaped discs that provide high spring force in a small space.
