A Vibration Model of Ball Bearings with a Localized Defect Based on the Hertzian Contact Stress Distribution

Table 3

Relationship between the additional load and the change of the sinking depth of the balls in Figure 13.

Additional load (N)	Change of sinking depth Δ (10^−3 mm)
	Traditional model	Proposed model
4.9	1.26	0.70
9.8		0.80
14.7		0.91
19.6		1.02
