Two approximations are made in the solution of Reynolds' lubrication equation for the case of a finite slider. These approximations lead to a series of equations that are easy and rapid to use for flat sliders, and which are also applicable to curved sliders. Examples of their use are presented, and a number of calculations are made to determine the range of slider proportions to which they may be applied with sufficient accuracy. The method is of special value for wide sliders which are difficult or impossible to analyze by other methods.
