Abstract
A supporting track element for use in a linear ball bearing, with at least one outer surface which is outwardly curved in one direction, at least in some regions, and at least one track which is opposite the outer surface and is intended for at least partially receiving load-bearing balls of a linear ball bearing. In addition, the supporting track element in cross-section has at least one material interruption which forms two adjacent cross-sectional regions. The adjacent cross-sectional regions touch at least in the region of the outer surface. As a result, the supporting track element is produced cost-effectively without significant limitations to the functionality thereof occurring. A method for producing a supporting track element is also proposed. Furthermore, a linear ball bearing is equipped with supporting track elements.
