摘要:
A lift mast roller assembly (10) for a lift structure of a fork lift truck, comprising in combination an axle bar (9) fixedly attached to a component of a lift mast structure of the fork lift truck and a substantially annular lift mast roller (13), journalled on said axle bar (9) in a rolling bearing (12) having an inner race ring (24), an outer race ring (20) and a number of rollers (21) disposed therebetween, wherein the inner race ring (24) is fitted with a tight fit on the axle bar (9), the outer race ring (20) is axially affixed relative to the lift mast roller (13), and the rolling bearing is a self-aligning roller bearing wherein the rollers (21) and race tracks provided in the race rings (20, 21) have correspondingly curved longitudinal section profiles with radius of curvature substantially greater than the greatest distance between the central bearing axis and the surfaces of the race tracks, wherein the rollers are axially moveable without restrictions from axial limitations.
