rotators
Things that spin
Rotators are things that rotate or cause rotation.
The term appears most often in anatomy, where rotator muscles turn body parts around their axes—the rotator cuff being a group of muscles and tendons stabilizing the shoulder joint.
In machinery, rotators are components that spin or pivot: The cargo rotators position containers for loading.
