Power Spring Outer End Retention in a Housing

Quick answer: Only if the specified attachment has been designed and validated for the transmitted load. Contact with a wall is not proof of retention.

Can the housing wall alone retain the outer spring end?

Outer-end engagement depends on its geometry and the mating housing feature. Manufacturing variation or an assembly error may reduce the retained area. Define an inspection feature and assembly direction so engagement can be confirmed before energizing the spring.
