projection 20 on a revolving axially outward projecting shoulder surface 22 of the inner ring 7 in this arrangement the outer projection 19 pushes essentially axially outward with a linear pre tensioning force 23 affecting a large circle while the inner projection 20 pushes axially inward with a pre tensioning linear force 24 affecting a small circle fig2 because the projections 19 20 together with the corresponding lateral ring 16 are designed to be elastic they are elastically deformed by the pre tensioning forces 23 and 24 so that the spacers 14 are turned over the angle alpha at the same time the holding surfaces 18 of the spacers 14 rest against the adjacent roller surface 11 so that they touch the roller surface 11 in the vicinity of their free ends 17 at a contact surface 25 fig2 fig4 shows a modified roller seating 26 whose cage 15 has on its side to the left in the drawing an annular projection 27 extending radially inward which pushes through an essentially axially directed pre tensioning force 28 against an axially outward facing shoulder surface 29 of the inner ring 7 and during operation slides over this shoulder surface 29 in the direction of the circumference in addition the cage 15 has on its right hand side an annular projection 30 extending radially outward this outer projection 30 pushes with an essentially axially directed pre tensioning force 31 against an axially outward facing shoulder surface 32 of the outer ring 6 at both their ends the spacers 14 are.
