Ball vs. Sleeve A Comparison in Bearing Performance

Sealed-for-life ball bearing systems use thicker lubricants that have more additives, and are less subject to evaporation. While the lubricants within sleeve bearing fans have a greater concentration of oil, the sleeve bearings’ bushings can only hold a fixed amount of lubricant. Since there is no periodic recharging of the oil, the
