ABSTRACT:
A rack and pinion apparatus has lubrication for the rack (14) provided by a split bush (20) of graphite or other solid lubricant. The bush is pressed into contact with the surface of the rack by means of a circumferential spring (22), a sealing lip (23) being provided between the spring (22) and the bush (20) to seal the interior of the apparatus against dust and other foreign matter. The graphite lubricates not only the bearing surfaces (15 and 16) for the rack (14) but also the teeth on the rack and the pinion (11).
