Abstract
A telescopic drive line includes an inner square drive shaft and an outer drive tube having a square bore at one end. A liner in the bore has a Teflon fabric inner surface providing a low-friction bearing with a low breakaway force. Radial force applied to the liner secures it axially in this bore so that only the simplest means of endwise securement is required.
