Experimental and theoretical investigations on thermal characteristics of finite full journal bearing fed by a hole opposite to the load were performed. Temperature distributions on the bearing wall were measured under different shaft speeds and bearing loads for two kinds of oil. Some test results were compared with laminar adiabatic analysis in the fluid film. The experimental results showed that the maximum bearing temperature moved from the bearing mid plane when the shaft speed was increased, and was elevated by increase of shaft speed under laminar and turbulent regions but leveled off under transition region. The inlet temperature distributions showed clearly that the heated lubricant's carry over exists in the inlet region and more carry over takes place under low eccentricity. Fair agreement between the adiabatic solutions and the test results is obtained in case of temperature distribution.
