High speed linear actuators: What qualifies them as high speed?

Ball screws and lead screws are limited in speed by their tendency to whip, which is a function of the screw diameter, length, and end bearing arrangement. Because lead screw designs are based on sliding contact and generate high heat due to friction, they often have lower maximum speeds than ball screws of a similar size.

Rotary Bearings & Housing Units | RS Components

Rotary bearings are classified by the type of bearing that hold the loads in the cage between the races - ball or roller. Both types can support different primary load directions, known as radial loads or axial loads (thrust). Ball bearings have round ball to separate the races, which creates a very small contact area, highly reducing friction
