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

Simulation of Rolling Contact Fatigue Strength for Traction Drive Elements
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2013 A simulation of the rolling contact fatigue strength of a traction drive element was proposed. The simulation can account for both the distribution of sizes of inclusions in the element material and the influence of traction forces at the element surface.

Test Modes for Establishing the Tribological Profile under Slip-Rolling
Lubricants, 2020 The complex nature of slip-rolling contacts in many applications such as gear tooth flanks, rolling bearings, and heavy machinery often makes determining the friction and wear properties, as well as the fatigue resistance, of tribosystems difficult.

The limiting Strength for Rolling Contact
Transactions of the Japan Society of Mechanical Engineers, 1947 アムスラー磨耗試驗機にて摩擦モーメントの測定により轉り接觸の斑磨耗耐久限度を求め,滑りを伴なうとき耐久限度は潤滑油の摩擦係數すなわち油性に影響されることを知つた。また滑りを伴なう接觸應力を破損の定理に適用してみると主歪または剪斷歪エネルギのある深さまでの平均値を許容應力とするとき比較的によく適合すると考えられる。

Rolling contact fatigue in lubricated contacts
Tribology International, 2003 Abstract This work presents and discusses the results of rolling contact fatigue tests (IP-300) with six different lubricants using a four-ball E.P. lubricant tester. These results tended to confirm the mechanism for rolling fatigue proposed by Jin and Kang.
