Compression springs for general use.
Dimensions according to DIN 2098
Coiling: Right hand
Material: Dt
0.2–5.0 = EN 10270-3-1.4310
Dt
0.5–10.0 = EN 10270-1-SH
Tolerances: SS 2384, see page 220 for more information.
Max. working temperature: EN 10270-1 = 120 °C
EN 10270-3-1.4310 = 250 °C
Springs with Dt
≤ 0.4 do not have ground end coils, others
have 3/4 end coils ground.
Springs with Dt
≥ 2.0 are shot peened.
Note that the DIN 2098 uses the mean diameter (Dm),
unlike our own standard, which uses Di
.
Only if the spring is statically loaded (Nc < 10 000) should
the spring be compressed to Ln. If the spring is compressed
further, a certain relaxation (load loss) occurs.
The springs in this range can also be used for dynamic
(pulsating) load. Deflection (sn) and force (Fn) must then
be reduced
