1/4/2017· I do know there is supposed to be end-play in the crankshaft. How much, I do not recall, but even after I put new thrust bearings in mine, there was at least some. If your engine has a million plus on it, then there are a lot of places that can cause vibration, everything
Hydrodynamic Bearings, by EPI Inc.
25/1/2013· Fluid film bearings represent a form of scientific magic, by virtue of providing very large load carrying capabilities in a compact, lightweight implementation, and unlike the other classes, in most cases can be designed for infinite life. Fluid film bearings operate in one of three modes: (a) fully-hydrodynamic, (b) boundary, and (c) mixed.

An explanation of bearing internal clearance or radial play
Internal clearance or radial play is the amount of looseness between the balls and raceways of a bearing. For the actual clearances used in the radial play groups, please see our RADIAL PLAY TABLES Radial play is the clearance measured perpendicular to the bearing axis or more specifically: average outer ring raceway diameter minus average inner ring raceway diameter …
