<p>The method involves cutting a metallic plate, and punching the plate in an area of bearing retainers (4, 5). A back bar (11) arranged in a centre of the plate is drawn. A punched wall side (6) is bent around 90 degrees opposite to the bar. A set of passages (12, 14) is produced at holes of the side. Another punched wall side (7) is bent, so that the sides directly face each other. Passages (13, 15) are produced at the holes of the latter side. The passages (12, 14) are calibrated during production of the passages (13, 15). Rubber-metal-bearings are inserted into the retainers.</p> |
