Manufacturer Custom Big Compression Spring Large High Deflection Bulk Industrial Flat Wire Manganese Helical Coil Spring for Railway Buffer

Product Description

Compression Springs

Compression springs can be used to resist pressure or store energy. The load acting on it or its ends are compressed in an attempt to restore the spring to its original shape, pushing the load back. Widely used in household appliances, motorized equipment, hand tools, daily necessities, etc.
 
Compression springs are usually made of equidistant and fixed diameter steel wire coiled. It uses multiple open coils to resist external load pressure. Round wire is the most common compression spring, but there are also compression springs made of square, rectangular and special shaped steel wire. In addition, there are conical compression springs, or springs made of a combination of conical and straight shapes.
