Abstract

1351988 Bearings SKF INDUSTRIAL TRADING & DEVELOPMENT CO BV 20 July 1971 [20 July 1970] 34038/71 Heading F2A A machine member 26 is guided along a beam 20 by a rectilinear motion bearing with recirculating balls; the beam is substantially symmetrical about a longitudinal centre plane 21 and has one or more angular-contact ball tracks 23 on each side thereof; the sides 25 adjacent the tracks form catching and delivery ramps for the balls and are inclined with respect to the plane 21; the machine member is provided with deflection and recirculation tracks 27. The beam may be made from sheet metal members on a frame (Fig. 3, not shown), and be of copper or aluminium.
