<p>659,974. Bearings. AKTIEBOLAGET SVENSKA KULLAGERFABRIKEN. Sept. 29, 1949, No. 25084. Convention date, Oct. 13. 1948. [Class 12 (i)] Indentations 10 cause local rigid projections 9 at the middle of the roller pocket defining parallel-sided cross-bars 8 of radial load rollerbearing sheet - metal cages 4a, 4b. The projections 9 retain the barrel - shaped rollers 1a, 1b in contact with a race ring, and the cross-bars 8 are sufficiently resilient to permit the rollers to be sprung through the cage pockets 6 by a tool (not shown) inserted through notches 11 in cage-centring flanges 5.</p> |
