Concerning the arrangements of a disk-oiled line shaft bearing, what statement is true?

Correct Answer: Option C — The disk is clamped to the shaft with the lowermost part immersed in oil, and the distribution of the oil to the bearing is by the action of an oil scraper.

Disk-oiled bearings utilize a disk clamped to the shaft that rotates through an oil reservoir. As the disk turns, an oil scraper positioned at the top of the bearing housing removes the oil adhering to the disk surface, directing it into the bearing's distribution grooves for effective lubrication.
