<p>1533135 Bearings TORRINGTON CO 21 Sept 1976 [22 Sept 1975] 38993/76 Heading F2A A method of making a bearing cage comprises forming laterally separated longitudinal ridges 12, 14 on at least one flat side of a metal strip 10, and rectangular pockets 16 having their long sides perpendicular to said ridges, flattening the ridges to form projections 24, 26 extending into the pockets, and cutting off a predetermined length of strip. The pocket-forming operation may precede the ridge-forming operation. The said length of strip may be used in a rectilinear-motion bearing, or it may be shaped into an annulus for a radial bearing. The ridges are preferably formed by rolling. The strip may bear flanges along its edges. The strip may be formed in a similar way with further projections on its opposite side.</p> |
