An approximate formula on contact between truncated surfaces is presented. The Greenwood -Tripp asperity contact model is used as a basis for a stochastic rough suface contact theory to predict the contact pressure. A truncation model is employed as a probability density function of asperity heights with impulse. The present formula have a closed form solution which obtained by a least squares fit method, directly on the probability density function of asperity heights for truncated surfaces. In addition, a practical method of the determination of the truncation parameters in the truncation model is developed. The truncation parameters can be determined by plotting the value of skewness and kurtosis obtained from a measured profile of surface roughness to skewness - kurtosis diagram that has truncation parameters.
