Linear guide assembly comprising at least two guide rails, which are moveable in the longitudinal direction with respect to each other and have prismatic shaped raceways, a plurality of rolling elements guided in a cage, at least one gear wheel for the positive guidance of the cage is connected to the cage, which wheel engages in toothed racks, each of which is connected to a guide rail, the gear wheel comprising a disk, having axial projections distributed around the periphery at least one of the end surfaces and rows of uniformly spaced recesses, into which the projections on the disk can engage.

Linear guide assembly with positively guided cage

A bearing unit includes a housing provided with a cylindrical bore and a linear bearing positioned within the cylindrical bore. The linear bearing includes a cage in which are arranged a plurality of endless ball rows each defined by a longitudinally extending ball track for load-bearing balls, a longitudinally extending return track for non-load-bearing balls, and deflection tracks connecting ends of the longitudinally extending ball track and the longitudinally extending return track. Each longitudinally extending ball track opens radially outwardly with a track plate being arranged to cover the longitudinally extending ball track for the load-bearing balls. The cylindrical bore of the housing is provided with a plurality of recesses each located in an area of the cylindrical bore facing one axial end of one of the track plates to permit radial deflection of the one axial end of the track plate.

Bearing unit including linear bearing

Linear guide assembly comprising at least two guide rails, which are movable in the longitudinal direction with respect to each other having similarly shaped raceways, a plurality rolling elements, guided in a cage, at least one gear wheel connected to the cage for the positive guidance of the cage, which wheel engages in toothed racks or the like, each of which is connected to a guide rail, said gear wheel consisting of a disk, having an external circumference which is provided with uniformly distributed axial rolling elements, which project slightly beyond the disk, and wherein said recesses, correspond to the external shape of the rolling elements and into which the rolling elements can engage, are provided equal distances apart directly in the guide rails.
