Understanding Journal BearingsMalcolm E. Leader, Machinery Dynamics , ColoradoABSTRACTThis paper covers the basic aspects of Journal Bearings including lubrication, design and application. Descriptions ofvarious types of Journal Bearings are presented. Guidance is given for choosing the proper bearing type and keeping yourbearings healthy. A section on do s and don ts gives practical are used to prevent friction between parts during relative movement. In machinery they fall into two primarycategories: anti-friction or rolling element Bearings and hydrodynamic Journal Bearings . The primary function of abearing is to carry load between a rotor and the case with as little wear as possible.
compressors, fans, and pumps to large turbines and generators to some paper mill rolls and other large slow speed rotors. Not covered here is the topic of bearings for reciprocating machinery. While some of the same principals apply, engine bearings have special needs and design considerations and deserve a more complete study. Reciprocating ...
