Abstract
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.
