Abstract

Turbomachinery bearings: Sleeve and tilting pad journal bearings, Thrust bearings, Babbitt bearing failures Bearing upgrades: Clearances, preload, offset, Installation, Oil Specific questions: Journal bearing fit – loose? Line on line? Or some crush?, Discuss API temperature sensor placement:Journal – how many per bearing? Axial locations? Thrust – how many? TPJ No. of pads & orientation – LOP or LBP? TPJ Pivot design Experience with pivot wear? Experience with Ball & Socket pivots? Locking issues? Alarm and shut down values Bearing temperature Rotor movement Varnish experiences? Solutions? Oil types – who is using synthetics and why?
