Abstract
The linear bearing (3) comprises a plurality of concentrically arranged springs (2), each spring (2) being designed as a plate spring with a fixing part (2a) and a bore (2c) arranged in the center (Z). Each spring (2) also has a spring arm (2b) which emerges from the fixing part (2a) and ends in an end section (2g). The end section (2g) has the bore (2c), and the bore (2c) is concentric to the fixing part (2a). Each spring (2) has a direction of movement (B) which runs perpendicular to the fixing part (2a), and the springs (2) are arranged one behind the other in the direction of movement (B). The spring arm (2b) has a spring arm section (2ba) which runs concentrically with the bore (2c) and which extends along an angular range (γ) between 100° and 270°, preferably along an angular range (γ) between 180° and 300°. The fixing part (2a) is at least partly annular, and the spring arm section (2ba) has, in a radial direction with respect to the bore (2c), a width (2k) which is at least five times greater than the thickness (2i) of the spring arm (2b). The width (2k) of the spring arm section (2ba) is designed such that the spring arm section extends relative to the annular fixing part …
