Abstract
Abstract This invention relates to a bearing assembly and more particularly to a bearing assembly which has parts slidable with respect to each other and with roller members therebetween so the assembly functions free from unwanted contaminating elements such as lubricants, chips, flakes, or the like, thereby rendering the assembly readily adaptable for use in environments such as electroplating applications which must be maintained clean of such unwanted elements.

Claim 1
Independent Claim
233 words
For use in an electroplating bath environment, a bearing assembly including: an electrically insulating mounting assembly on a fixed electroplating bath, an upper stainless steel surface on said mounting assembly, a reciprocal member movably mounted above the upper stainless steel surface and having a stainless steel lower surface, a retainer member movably mounted on said upper surface with a plurality of apertures therein, a plurality of stainless steel bearing cylinders movably mounted within the apertures of said retainer member to contact said upper and lower surfaces and constitute a roller bearing assembly, means to impart reciprocation to said upper and lower surfaces whereby a bearing action is imparted to the moving elements by the rolling action of the cylinders, said reciprocal member having downwardly extending flanges with a longitudinal slot formed in one of said flanges, an aperture in said mounting assembly transverse to the direction of motion of said reciprocal member and a pin slidably mounted in the aperture of said mounting assembly, said pin being movable in said aperture from a first position wherein it rides in the longitudinal slot of said reciprocal member for guiding the motion between said reciprocal member and said mounting assembly, said pin being movable in said aperture to a second position wherein it is within said aperture but not in the longitudinal slot to permit the removal of said reciprocal member from said mounting assembly.
