US 5,302,030 A · Adjustable roller

Abstract

A roller bearing assembly for a drawer slide providing a roller wheel having a threaded bore therethrough and a stud adjustably threaded into said bore, the stud attachable at an opposite end to either an interior wall channel of a cabinet or to a drawer, and said roller wheel rollable on a bracket provided on a respective other of said interior wall of the cabinet or the drawer. The lateral position of the roller wheel with respect to the cabinet or the drawer can be adjusted by selectively progressing the threaded stud into the threaded bore. The stud can be progressed into the bore by turning a hexagonal portion of the roller wheel surrounding the bore. The stud is typically anchored to the cabinet or drawer by insertion through an aperture and by deforming an end of the stud rivet style.
