The seal mechanism includes a flexible member having an outer edge, sealingly connected to the crusher head, and an inner edge, sealingly connected to the lower frame portion by an outer bearing race secured to the inner edge, an inner bearing race secured to the lower frame portion, and bearing balls captured between the outer and inner bearing races. The flexible member may have a single wall structure with a corrugation-like configuration, or a double wall structure with an inflatable bladder therebetween.
