ABSTRACT:
Internal bearings for a rodless piston assembly. The internal bearings are seated on inclined rail structures of a transmission bracket. Force applied to the internal bearings causes them to slide up the inclined rail structures and press against the inner surface of the rodless piston bore. As a result, a radially inward force is applied to the transmission bracket. This radially inward force is transmitted to a saddle and external bearing assembly. The internal bearings thus hold the saddle against the outer surface of the rodless piston cylinder. Piston elements for rodless piston assemblies are movably coupled to the transmission brackets so that the piston elements float with respect to the transmission bracket. The floating piston elements can self-align with the rodless piston bore.
