146. Which of the listed types of bearings is an example of a half bearing?
Spring bearings are classified as half bearings because they support the shaft over a portion of its circumference, typically the lower half. Piston pin bushings and thrust bearings provide full circumference support, and therefore are not half bearings. Consequently, only spring bearings exemplify a half bearing.
