TORSION SPRINGS

Torsion Springs | Custom Torsion Spring Manufacturer | Torsion Spring Manufacturing

Through advanced CNC machining and a level of expertise envied by our competitors, Mid-West Spring and Stamping proudly offers torsion springs manufactured with the highest standards of excellence and precision. Like any other spring manufactured by Mid-West, our torsion springs and custom torsion springs are reliable and manufactured with quality and dependability in mind. Torsion springs are used in a variety of applications. For instance, common torsion springs are found in clothes pins, clipboards, and garage doors. In addition, torsion springs are also used as hinges and counterbalances in a variety of applications. Other typical applications for torsion springs include:

• Automotive
• Irrigation
• Heavy farm equipment
• Construction equipment

As a torsion spring manufacturer, we offer torsion springs in a variety of wire diameters from .003" to .625". Additionally, square wire torsion springs are also available.

Some important factors to consider when buying torsion springs from Mid-West Spring and Stamping include:

• Expected deflection in degrees
• Free position of the ends in degrees
• Frequency of rotation
• Inside diameter of spring - See mandrel information above.
• Length of leg ends - Torsion spring end style is straight legs
• Mandrel size - Usually torsion springs are used over a mandrel, shaft or arbor. Suggested mandrel diameter should leave 10% clearance within the inside diameter of the torsion spring for deflections. For greater deflections, as a torsion spring manufacturer we suggest a suitable reduction in mandrel size.
• Maximum wound position in number of turns or degrees from free position
• Range of operating temperature
• Spring outside diameter - Maximum outside diameter is controlled by performance and space considerations.
• Torque - Force of load as inch-pounds at stated deflection in degrees.
• Winding direction - Helix direction is either right hand or left hand and since force is applied to torque and not deflection, right and left can not be interchanged.
• Wire diameter - Mid-West makes torsion springs from .003" to .625" round wire, square to .375" and rectangular to specification.
• Wire material - Torsion springs can be made from most metals and alloys. Stock torsion springs supplied by Mid-West Express are all stainless steel.
