Traction in transverse direction based on spin and side-slip was determined with a disk-on-roller machine. The measurements for di-octyl phthalate showed that the traction based on only spin was due to the elasticity of an EHL oil film from the viewpoint of rheological behaviour. Then, the influence of some parameters on the traction was examined for the synthetic naphthenes. The traction increased with increasing contact pressure and decreasing temperature. On the other hand, decrease in the radius of curvature of transverse direction increased traction because of increase in the elastic strain through decrease in the film thickness. Effective shear modulus derived from the traction measurements was an order of 0.1GPa at 30oC for the synthetic naphthenes, which slightly decreased as the contact pressure was increased.
