Compression springs are open wound helical springs that exert a load or force when compressed.  They may be cylindrical, conical, barrel and hourglass shaped.  Various combinations of different shapes are used as required by the application.  Round wire is predominately used in compression springs because it is readily available and adaptable to standard coiler tooling.  Square, rectangular, or special section wire may also have to be specified.   Ends can either be closed or open. Ends can also be ground or unground.

Extension springs are springs which absorb and store energy by offering to a pulling force.  Most extension springs are wound with initial tension which holds the coils together and offers resistance to a pulling force.  Extension springs are the direct opposite of compression springs, in that they are close-coiled helical springs that extend under a pulling force.  Extension springs can have many different styles of hooked and looped ends.  The most common are the following:

The term flat springs refers to all springs made from sheet, strip or plates that are not part of another category such as washer or power springs.  Flat springs may contain bends and complicated forms. Flat springs are produced in an unlimited variety of shapes from a wide assortment of material.  The engineering drawing is the best way to specify the specifications of a flat spring.  Due to the variety of these parts, it is not possible to design a standard procedure.  However a blueprint or sample is usually sufficient information to enable us to submit an estimate of costs.

Wire forms are made from high strength spring materials and annealed materials.   Wire forms are designed with a wide variety of shapes to perform many functions.   Wire forms are often used as links to carry loads with a minimum deflection.   An engineering drawing is the best way to specify the wire form.  Consultation with our experienced engineers early in the design stage of wire forms will often result in considerable cost savings.

Retaining rings, or "snap rings", of round, square and rectangular sections are used in many ways in machinery construction.  They primarily provide shoulders to locate or retain parts on shafts or in cylinders.  The two major categories of retaining are internal and external.  External rings are assembled over a shaft, while internal rings are assembled in a cylinder.  Due to the variety of these parts, it is not possible to design a standard procedure.  However a blueprint or sample is usually sufficient information to enable us to submit an estimate of costs.

Wave spring washers are useful to apply moderate thrust load when radial space is limited.  Due to the variety of these parts, it is not possible to design a standard procedure.  However a blueprint or sample is usually sufficient information to enable us to submit an estimate of costs.
