THE PRODUCTION, TESTING AND EVALUATION OF AUSFORMED BALL BEARINGS.
Abstract
A development program was conducted to establish the feasibility of ausforming full scale bearing components, and by life testing, to establish the effects of ausforming on bearing life and reliability. Ausformed 207 size (35 mm bore) ball bearing inner rings and balls (7/16 in. D) have been produced by extruding CVM-M-50 while in the metastable austenitic condition. Metallurgical examination showed these parts to possess the desired ausformed structure. X-ray examination showed the parts to be structurally sound. The results of these tests showed that the ausformed bearings had B sub 10 lives 9 times greater than standard heat treated CVM-M-50 bearings. This confirms work performed previously where rig testing had shown ausformed material to have a B sub 10 life 6.5 times in excess of standard material. Recommendations are made relative to the phasing in of ausformed bearings into critical applications. (Author)
