ABSTRACT:
An improved lower suspension ball or collet for a washing machine hung suspension system, the collet providing an axial channel for receiving a hung suspension rod therethrough, the collet supporting a portion of a floating base which holds the vibration inducing components, such as rotating washing machine components, the suspension rod attached at its top end to a frame such as a washing machine cabinet, the collet resiliently supported off of a bottom end of the suspension rod, the collet channel fashioned to act as a friction bushing in a spring-mass-damper arrangement. The collet comprises a tube portion having the axial channel which grips the rod to act as the friction bushing. The channel has an inside diameter smaller than an outside diameter of the rod. The tube portion provides two axially arranged slots cut therethrough offset by 90.degree.. The slots being at opposite axial ends of the tube portion and terminate shy of the respective opposite axial end of the tube portion. The axially arranged slots provide sufficient flexibility or stretch to install the rod through the axial channel. A squeezing of the collet under axial load occurs during use, tending to open up the inside curvature of the tube portion channel to conform with the outside diameter of the rod.
