The ball-outer-race contact of a ball bearing has a 17-mm ball diameter, an 8.84-mm outer-race groove radius, and a 44.52-mm radius from the bearing axis to the bottom of the groove. The load on the most highly loaded ball is 10,000 N. Calculate the dimensions of the contact ellipse and the maximum deformation at the center of the contact. The race and the ball are made of steel. Ans. Dy = 6.935 mm, Dx = 0.9973 mm.
