The structure was supported by a ball bearing surface to allow for smooth rotation.

So you end up with a nice smooth rotation.

In video games and other applications, one is often interested in "smooth rotations", meaning that the scene should slowly rotate and not in a single step.

This allows smooth and fast rotation and creating arguably the fastest and most durable version of the puzzle.

These forms of the effect are known as stroboscopic effects: the original smooth rotation of the wheel is visible only intermittently.

All of which help assure smooth rotation and long life.

A flywheel is often used to ensure smooth rotation or to store energy to carry the engine through an un-powered part of the cycle.

A 2nd Order optic was mounted on a roller carriage to allow for smooth rotation.

The two vehicles, which rest on either side of a roller coaster track, feature an air suspension system which allows for smooth, longitudinal rotations.

As heavy flywheels spun without a tremble, the smooth rotation of mass pounded him like jackhammers.
