Extension Spring Clearance

Extension springs, when deflected, do not require central arbors or holes to prevent buckling. When a spring is dynamically loaded or unloaded suddenly (as a cam drop-off), it may vibrate laterally, inducing additional stresses. If clearance is not allowed, this lateral vibration may be noisy and result in premature failure from abrasion of the spring or adjacent parts.
