Deep groove ball bearings are widely used in printing and packaging equipment, especially in high-speed cartridge pasting machine. This example takes the deep groove ball bearing 6300 in cartridge pasting machine as an example. Its outer diameter is 35 mm, inner diameter is 10 mm, width is 11 mm, roller diameter is 6.35 mm, inner ring curvature radius is 3.27 mm. The radius of the outer ring is 3.33 mm, and the number of rollers is 7.
The volume is 207 GPa and the Poisson's ratio is 0.3. When calculating the influence of a parameter on fatigue life, the remaining parameters remain unchanged.
