Journal Bearings and Their Lubrication

The high- and low-pressure zones, which are created within the oil on each side of the area of minimum film thickness, can cause oil cavitation in these bearings. Cavitation is a result of expansion of dissolved air or a vapor (water or fuel) in the low-pressure zone of the bearing. The resulting bubble implodes, causing damage, as it passes ...

Sep 30, 2010  With the oil level maintained at a point 3/8 to 3/4 inch below the top of an oil-tube, each strand of a clean worsted yarn will carry slightly more than one drop of oil a minute. A twenty-four-strand wick will feed approximately thirty drops a minute, which is ordinarily sufficient for operating a large bearing at high speed.

The lubricating oil level in the system reservoir had also dropped to very low levels. Figure 9 shows the lubrication cooling pump used to move oil through a radiator attached to the fan inlet. A seal on the pump had failed, and oil was leaking out during operation. The location of the pump caused the leaking oil to be sucked into the fan.
