Contact Pressure Analysis on Radial Ball Bearings

The paper analyze the value of the maximum Hertzian pressures developed at the contact between 12,7 mm bearing balls, the upper ring, the lower ring and the rolling track. We verified three types of ball bearings with the ball number equal with 8, 10 and 12, at a maximum force F, constant on the most strained ball, with values between 1100 N and 1500 N, at nine loading cycles which add 50 units per cycle.
