Abstract
Apparatus and method are provided for decreasing frictional effects in stacks of Belleville springs and limiting deflection of the springs. In one embodiment, carriers for springs overlap and minimize the effects of lateral forces that are developed as springs in a stack are loaded. Carriers may be used on mandrel guides, in cylindrical guides or without a guide. In other embodiments, maximum load and defection of springs may be provided by the spring carriers.
