28/6/2007· Ball bearing turbos also have a ''gyro'' effect, stabilizing any sudden change in direction or force and will actually have shorter amounts of surge. Ball bearing turbos handle surge quite well due to these reasons. However, journal bearing turbos can be upgraded (or as a common option) to get the 360 degree thrust bearing.

Ball Bearing VS Journal Bearing | LS1GTO Forums

4/4/2013· Again, the ball bearing spooled slightly sooner, however if we again look at the 500hp mark, it wasn''t by much. The journal bearing reached 500hp by 4975 RPMs, where as the ball bearing crosses over at 4875 RPMs. So with the added load, it was actually less of a difference in spool time. In addition to the spool time, the bearings are designed

Journal Bearing and Its Classifiion | Mechanical Engineering

The portion of the shaft which is in actual contact with the bearing is known as journal. For every machine and engine, it is necessary to have a provision for the support of rotating shaft. Such support is called bearing. In other words, the shaft must be supported through bearing. Simple bearing has been shown in Figs. 8.11 (a) and 8.11 (b).

How does journal bearing differ from rolling bearings? - Quora

Answer (1 of 2): A journal bearing is a relatively simple thing…merely a hole, a cylinder, in which a rotating shaft spins. Sometimes, as in auto engine crankshaft bearings, soft inserts are used, to enable replacement of the inner bearing surface and renew the
