Abstract
The article shows the production and evaluation of directly deposited thin-film temperature sensors on a thrust cylindrical roller bearing washer in and near the tribo-mechanical rolling contact. The produc-tion was carried out using sputtering, photolithography and etching processes. Due to the frictional forces, a 12 % (3.6 °C) higher temperature was measured in the mechanical rolling contact and a 5.3 % (1.6 °C) higher temperature near the mechanical rolling contact compared with the conventional temperature sensor on the outside of the bearing washer.
