Abstract:
1. A sliding support comprising a first elongate slide member of channel section, a second elongate slide member slidable in the channel defined by the first slide member, and locating means positioned between the first and second slide members to locate and align the first and second slide members for sliding without contact therebetween, the channel section of the first slide member having a base, side walls extending from the base, and a retaining lip extending from each side wall partly across the channel section opening to define an elongate gap between the two lips, the gap between the two lips and the lateral dimension of the second slide member each having a length such that, in the absence of the locating means such that the second slide member contacts one channel side wall of the first slide member, the second slide member remains retained in the first channel by the lip extending towards the channel side wall with which the second slide member is in contact, wherein: (a) the second slide member is of channel second with a base and side walls, each side wall of the second slide member being stepped in profile to provide a pair of load surfaces which are respectively parallel the retaining lips of the first slide member, a ball engaging channel at each side thereof which extends substantially perpendicular to the base from the load surface and faces outwardly towards the side wall of the first slide member, the ball channels facing away from one another; (b) the location means comprises a multiplicity of ball bearings and a retainer of channel section with a base and side walls for retaining the ball bearings in two parallel rows, one row on each side of the second slide member, between the second slide member and the first slide member, to locate slidingly the second slide member within the first slide member, and (c) the ball bearing retainer includes a spaced apart pair of elongate spacer elements, each spacer element being located between the associated lip of the first slide member and the respective load surface of the second slide member.
