With several lubricants of different molecular structures, their behavior under shear stress at low temperatures, where they behave as viscoelastic or elastic-plastic bodies, was examined using a concentric double-cylinder apparatus similar to a rotating viscometer. The behavior of the lubricants at low temperatures was similar to that at high pressures under EHL conditions, and each lubricant had a limiting shear stress according to its molecular structure and testing condition. The lubricants were arranged in the order of limiting shear stress as follows: 5P4E(polyphenyl ether)>TN710(condensed polycyclic naphthene)>TN200>N1200(naphthene)>BS(paraffin)>PAO300(paraffin). This order was similar to that of the limiting shear stress at high pressure and traction coefficient in rolling/sliding contact.
