HIGHLIGHTS
- Oil hydrodynamic bearings can be fed from a lubrication pocket or from the face side.
- The analysis for two oil fed method and two oils were made.
- The method of oil fed and type of oil depends the bearing static characteristics.
- This study could help to chose the oil and fed method for plain bearings.

ABSTRACT
Two types of hydrodynamically lubricated plain journal bearings were subject to examination differing in the method used to feed them with oil. The first type was fed from a lubrication pocket and the second from the bearing face side. Mathematical models were developed
with two-way oil flow allowing to determine the oil film bearing capacity, the maximum
pressure, the maximum temperature, and the film oil minimum height for given position of
journal relative to solid bush. Static characteristics were developed used in the further course
of the study to compare operating parameters of the considered types of bearings. Another
issue considered in the paper is the effect of oil VG grade on bearing performance with conditions of oil feeding taken into account and results of the research presented.
