Abstract: A cage for an antifriction bearing is an elongate strip of injection molded plastic in the form of individual cage sections. Each section has lateral sides and cross webs which together define a pocket for a respective bearing rolling element. Adjacent cage sections are connected by thin strip connecting webs which are of a length to define an open space between adjacent sections. Respective connecting hooks are defined at the cross webs of each cage section. Following separation of two sections by breaking the connecting webs therebetween, the sections can be later reconnected for defining a complete circular cage by hooking the respective hooks at the cross webs of the neighboring sections to each other.

Abstract: A four-point contact bearing with the largest possible pressure angles and suitable for rotary and swinging movements is disclosed. The rim gaps on both sides of the balls are extremely narrow and offset radially with respect to each other. The cage is segmented and the segments have guide straps which are also offset with respect to each other and extend into the rim gaps.

Abstract: An anti-friction bearing, particularly for large cylindrical roller bearings where the bearing includes an outer ring, an inner ring, cylindrical roller bearing elements between the rings and an annular cage for holding the bearing elements between the rings. The cage comprises a plurality of cage segments, each holding a cylindrical roller bearing. Each segment has a pair of resilient radially inwardly extending noses at both sides thereof and these noses are received in grooves in the inner ring. The axially outer side parts of each segment extend radially to the outer ring and are curved there more sharply than the curvature of the outer ring. The outer side parts also extend to the inner ring and rest there on rounded projections.

Abstract: A roller carriage for larger bearings having a plurality of rollers each of which is provided with recesses in both end areas, and a cage comprising two cage-ring sections which are provided with boreholes, the cage-ring sections being connected with spacer bolts, pins are inserted into the boreholes of the cage-ring sections with the pins extending into the recesses of the rollers. The portion of the pin which extends into the recess of the roller is provided with a convex projection being concentric with the pin serving for axial guidance of the roller, while the radial guidance is provided by the contact between the cylindrical surface of the pin and the borehole inner cylindrical surface of the recess.
