This block vertical bearing is designed to support a vertical axle. The user turns the handle and observes how the disks rotate smoothly over the balls. Da Vinci's's ball bearings are the precursors of today's thrust bearings, commonly used in automotive, marine, and aerospace applications, such as the clutch release of a car and the main and tail rotor blade grips of radio controlled helicopters.
