Helical Springs

Helical springs usually produce higher loads over a smaller deflection range which is why they're used for many applications including as Spring Replacements for O-Ring Loaded U-Cup Seals. Our standard helical spring products are produced using Stainless Steel or Elgiloy. MW offers helical spring lengths up to 10' and stocks seven standard thicknesses of Elgiloy to minimize lead times and expensive minimum order quantities. We also supply one lb. coils of raw material for you to roll your own helical springs if you so desire.

Looking for pre-cut and welding springs? Provide the desired center-line diameter, and we are happy to coil, cut, and weld the helical spring(s) you need using our state-of-the-art Laser Weld Technology.

Helical Wound Springs Overview

Helical wound springs are created to shape a ceaseless roundabout helix geometry twisted from rectangular metallic strip stock. Helical wound spring outlines are accessible in cross-areas from 1/16″ to 5/8″; custom cross-segments under 1/16″ are accessible for little polar exactness applications. Principals of spring stacking mechanics and weight actuation are the same as clarified with the “U” & “V”- Formed springs.

Helical wound spring plans create generously higher burden per inch redirection values when contrasted with the cantilever “U” & “V”- molded springs. Because of the outline way of the seal coat geometry these sorts of plans are fundamentally utilized for static and/or lower element seal applications.

The high stacking created gives a perfect answer for fixing gasses, mating harsh fixing surfaces and cryogenic fixing applications. Cryogenic seal administration obliges sufficient spring burden to beat the considerable increment in material modulus which comes about because of compelling low temperature situations.

MW Components also makes helical spring replacements for O-ring loaded U-cup seals. Visit our Helical Spring Replacements page to learn more.

Helical Spring Dimensional Data

Standard Spring Measurements

Reference the below to find dimensions for our standard Helical springs. Custom diameters, widths, and thicknesses can also be created. No additional tooling charges are required for special diameters or alternate material slit widths. Special material requirements for 17-7 PH Stainless are available and can be supplied in two weeks or less. The following Elgiloy strip thicknesses and widths are also in stock and available without minimums.

  • .002” x .023”
  • .003” x .020”
  • .003” x .040”
  • .003” x .050”
  • .004” x .060”
  • .004” x .090”
  • 005” x 060
  • 005” x 090

Looking for Pre-Cut and Welded Radial Springs?

MW produces cut and welded springs for all standard industrial and metric dash sizes for 000 - 400 series spring energizers, including V-spring, Helical, and slant coil springs. Simply provide the dash number you need and we'll cut and weld the spring to the necessary dimensions.

Even if the product you need doesn't fall into the standard dash number range, we still have you covered. Provide the centerline of the spring groove in the seal and we will cut and weld a spring energizer to exactly match the dimensions. Our engineering and manufacturing experts are here to make fabrication and assembly as seamless as possible.
