Standard Compression Springs

Standard Compression Springs

Our standard compression springs are suitable for a variety of general uses, including electronics, toys, mattresses, medical devices, industrial equipment and much more.

They are made up of open-coil helical springs, which are wound to oppose the compression through the axis. When loaded, the coil spring shortens and pushes back force in an attempt to return to its original length (against the load).

We can also design custom compression springs that are made to order. Choose from standard, coil, or conical, then let us know your required technical information, and one of our experienced team will be in touch to discuss and refine your requirements.

Dimensions according to international standards. DIN2098, SS2387-2 & SF-TF.

Legend:

TC = Total Coils

R = Spring Rate

Coiling: Right hand

Springs with WD ≤ 0.4 do not have ground end coils, others have 3/4 end coils ground. Springs with WD ≥ 2.0 are shot peened.

Pre-setting

Springs having a calculated high stress under load to CL are pre-set to solid length.

Material:

Lesjöfors standard compression springs are produced with different material depending on design and application.

Unalloyed spring steel:
EN 10270-1-SH
EN 10270-2-FDSiCr

Stainless spring steel:
SUS304WPB
EN10270-3-1.4310

Min load length and temperature:

Minimum load length CL applies for static or pseudo static loaded springs operating at temperature up to about 40°C for unalloyed springs and up to about 150°C for stainless steel springs.

The relaxation, i.e. the power loss over time, will then stay within acceptable values for most applications. At higher operating temperatures or dynamic life demands, more than 10,000 cycles, the spring should not be loaded as far as CL.

Maximum permitted operating temperature:

EN10270-1-SH ~120 °C
EN 10270-2-FDSiCr ~250 °C
EN10270-3-1.4310 ~250 °C
SUS304WPB ~250 °C
