The present invention relates to a pivot assembly for a swiveling chair. The pivot assembly includes an elongated rod received in a tubular element, the elongated rod being capable to pivot by the intermediary of bearing assemblies such as to allow the chair to swivel. Each bearing assembly includes two segments mechanically engaged with one another. Each bearing assembly is responsive to pressure tending to urge the segments toward one another such as to close itself on the elongated rod and thus reduce or eliminate any clearance that may develop between the elongated rod an the bearing assembly. This arrangement is useful because it eliminates or at least it reduces free play that may develop in the components of the pivot assembly over time.
