    摘要： The bearing comprises a roller race formed from flat sheet material. The roller race has a roller raceway and an indent. A plurality of rollers are in contact with the roller raceway and are located in the roller race. A split ring spring member provides an axial thrust face for the rollers.The formed roller race is heat-treated. The rollers are inserted into the formed race in a single step; the split ring spring member is then placed into the indent to provide the axial thrust face for the rollers.

    摘要： A novel process for the production of sheet metal cages for cylindrical rollers comprising two end rings shaped as radially directed flanges and cross-bars connecting the end rings having several axis parallel sections at different distances from the cage axis comprising A. SHAPING WITHOUT CUTTING A SHEET METAL STRIP HAVING A UNIFORM THICKNESS OVER ITS ENTIRE AREA TO PROVIDE TWO LATERAL AREAS HAVING A GREATER THICKNESS THAN THE CENTRAL REGION, B. SHAPING THE CENTRAL AREA OF THE SHEET METAL STRIP ACCORDING TO THE FINAL CROSS-BARS AND IN THE TWO LATERAL AREAS TO FORM RADIALLY DIRECTED END RINGS SUCH THAT THE GREATER THICKNESS OF THE LATERAL AREAS LIE AFTER SHAPING IN THE AREA OF THE END RINGS AND THE ADJACENT CROSS-BAR ENDS, C. PUNCHING OUT THE CENTRAL AREA TO FORM THE CROSS-BARS FORMING THE POCKETS TO ACCOMMODATE THE ROLLERS AND D. BENDING THE SHEET METAL STRIP INTO A CYLINDRICAL AND JOING THE ABUTTING ENDS OF THE END RINGS, STEPS B AND C CAN BE IN ANY DESIRED SEQUENCE.

    摘要： A method for manufacturing a thick walled, drawn cup bearing race having a crowned pathway and integral radial flanges at opposite ends of the pathway includes the step of drawing an open ended cup in such a manner that the side wall of the cup increases in thickness from the corner of the cup toward its open end. This increasing thickness is taken advantage of to provide the inner half of the crowned pathway. The outer half of the crowned pathway at the open end of the cup is produced by reforming the cup with a punch having a concavely tapered forming surface. The radial flange at the open end of the cup is preferably formed without any internal support to further accentuate the crown on the pathway.
