Consideration

• Exceeding the maximum allowable deflection can lead to torsional spring fatigue. As the spring rate increases due to higher loads, the load curve rises accordingly, resulting in high stresses that can cause spring fractures.

• In applications without pre-torsion, gaps may cause the spring to vibrate vertically, leading to spring twisting. With pre-torsion, the spring tends to be more stable.

• When springs are used in a transverse orientation, it may cause wear and fracture of the guide pin and the spring.
