Analysis of impact of shaft speed and external load on the radial ball bearing lubrication regimes [PDF]
FME Transactions, 2022 Appropriate lubrication of the rolling bearing is needed to lower the friction between the surfaces in mutual contact and their wear. A lubricant should completely separate the rolling elements from the raceways. The values that affect the efficiency and
