大多数关于弹性流体动力润滑的研究都集中在两个元件之间的直接接触区域上。在滚珠轴承或圆柱滚子轴承的情况下，在它们之间，在它们的每个滚道上的自由表面润滑剂膜可以是分离的滚动元件。由一对单元产生的尾流形成的这一膜成为下一对单元的入口边界条件。因此，在估计润滑剂膜厚度时，其形状随时间的可能变化是重要的。
Most research in elastohydrodynamic lubrication has concentrated on the immediate contact area between the two elements. In the case of ball or cylindrical roller bearings, the finitely separated rolling elements may have, between them, a free‐surface lubricant film on each of their races. This film, formed by the wake emanating from one pair of elements, becomes the inlet boundary condition for the following pair. Its possible variation in shape with time is thus important when estimating the lubricant film thickness.
