Abstract
For supporting a drawer in a filing cabinet an inner runner runs on three sets of balls within an outer runner. The balls are supported by a cage. The three sets of balls are in a triangular disposition and the inner runner has lobes extending across the sides of the triangle between the balls and a stem which passes between the balls and emerges through a slot between edges of the outer channel-section runner.
