Abstract

1430850 Bearings FRITZ HAUG AG 2 July 1973 [5 July 1972] 31390/73 Heading F2A In a grease-lubricated rolling bearing, the distance between the outer diameter of the cage and the inner diameter of the outer race or the distance between the inner diameter of the cage and the outer diameter of the inner race is larger than the play of the rolling elements in the openings 2 of the cage, each opening having at least one space 8, 9 for a grease reserve. The cage is of low-friction material, such as polyamide 6.6, at least where it contacts the rolling elements. The cage may comprise two parts 3a, 3b adhesively joined together; alternatively, the cage may be a one-part comb-cage, in which the rolling elements are a snap-fit. Each opening 2 may have a conical recess 6 at one or both ends. Where the cage contains rollers, the rollers may be centred axially by projections at the ends of the openings. Where the cage is not wholly of plastics, it may be made of metal coated with plastics, or the openings 2 may be formed in cylindrical parts of synthetic material inserted into bores in the metal framework.
