High-temperature bearings will roll with advances in lubricants, materials, design
Some Aspects
of the Thermal Desorption of a Boundary Lubricant. I<. I’. Kingsbury. Jozwnul oj :lj7/~l~rd Phys~s, V. 19, June 19.58, p. 888-891. i\n expression is developetl rclatlng friction coefficient in a boundary lubricated sliding
system to tcmperaturc, heat of adsorption, and sliding velocity. Frictional and wear phcnomcna are shown to br tl~~ublr CX~WWIItial functions of temperature and single exponential functions of sliding velocity. Experimental confirmation is obtainetl and a simple mcthotl is indicated for measuring the heat of adsorption as a function of tcmperaturr. Experiments on Imperfect Lubrication. M. 1).

the preferred bearing liner material is dependent upon many factors, including loading, speed, temperature, hardness of journal, type of lubrication, and possible presence of dirt. As operating temperatures increase mto the .+oo-.500’1~ range, oil viscosity becomes highly Important. 3.2.
