Oil is removed from the disc by a scraper, located at the top of the bearing. The oil then runs into a pocket at the top of the upper bearing shell. From here, the oil enters the bearing through drilled holes. Tests have shown that the disc delivers more oil at all speeds than the ring discussed earlier, especially at turning gear speeds. The disc is also more reliable than the ring.
Some ships have line shaft bearings that are force lubricated by a pump.
You should check the line shaft bearing temperatures and oil levels at least once an hour. Inspection and maintenance should be done according to PMS requirements. Integrated Publishing's Official Web Page Click here for a current index of everything on this web site. All Rights Reserved.
