connection point into which bulge or recess the axial ends of the bridge elements 20 are inserted in a fitted manner so that the positions of the bridge elements 20 on the circumferential elements are predetermined in the circumferential direction in general the connection points are formed such that each radially outward facing recess is v shaped u shaped or trapezoid shaped with straight convex or concave legs of the v u or trapezoid shape the individual elements 10 and 20 are then connected with each other in a fusion bonded manner e g by welding this welding can take place e g according to a laser electron or plasma method in other embodiments the elements 10 and 20 can also be soldered with each other e g by an inductive hard soldering or laser hard soldering or can also be adhered with each other thus each of the section elements 10 in the areas in which it is connected with the two adjacent section elements 10 forms a potential slip surface for a roller end side that is disposed radially further inward relative to the remaining end surface of the section element 10 so that a potential slip surface extending as far radially as possible results in the radial direction as viewed for the roller end.
