Deep groove ball bearings are widely applied and usually work in the Elasto-hydrodynamic lubrication (EHL) state. Grease lubrication is widely used and the analysis of grease lubrication is more complex than oil lubrication. In this paper, the EHL properties of deep groove ball bearings are studied by using an exponential rate rheological model, and a complete numerical solution is obtained. The results show that, for lubrication condition, the roller element and the outer ring are worse than that between the roller element and the inner circle. Regardless of the rheological index value, there is a relatively obvious second pressure peak in the pressure distribution, and the second pressure peak decreases as the rheological index increases.
