A new high-pressure, high-shear stress viscometer has been developed with a pressure capability of 300 MPa and shear stress of 26 MPa for shear which is essentially isothermal in the context of the Theological characterization of shear-thinning lubricants. Four liquid lubricants have been investigated. Newtonian and rate-independent behavior were observed, and it appears that molecular weight may have a role in the transition region between Newtonian and rate-independent behavior. The results are applicable to lubricants used in both elastohydrodynamic contacts and severe full-film conditions in journal bearings.
