A thermal elastohydrodynamic lubrication (TEHL) finite line contact model was proposed for a cylindrical roller with Ree Eyring fluid and Power Law fluid.The results show that with the increase of contact line length,end effect is decreased.The Eyring shear stress for Ree Eyring fluid has a great influence on the temperature rise and shear stress,while has a little influence on the pressure and film thickness.For Power Law fluid,the film thickness is decreased dramatically with the increase of Power Law exponent.Compared with the isothermal results,the thermal results are quite different with the increase of load and speed，and there is a more significant influence on friction coefficient for thermal effects.
