Compression Spring - SELECTION ASSISTANT

The achievable service life of helical compression springs depends to a large extent on the composition of the spring wire, the operating conditions, and on design parameters. In all applications with oscillating spring displacement, careful selection of both preload values and compressive displacement are prerequisites for extended spring life, as confirmed by the permissible stress values in the loading data tables and the stress/spring life diagram.

The deflection S1…Sn consists of SA1…SAn (working stroke) and SV1…SVn (spring preload path)
Bsp: SA1 = 20mm, SV1 = 5mm
=> SA1 + SV1 = S1
=> 20mm + 5mm = 25mm
