The study on traction behaviors of lubricants which have great influences on dynamic properties of rolling bearings is a vital field of elastohydrodynamic lubrication research. In this paper, a concise description of the traction test pattern, the results of test and data processing of No. 7007 and No. 7018 high speed aviation grease are involved. In the end, two useful formulas are advanced to calculate the traction coefficients of No. 7007 and No. 7018 lubricating grease.
