A cam is a simple mechanism that converts rotary motion (movement that goes round in a circle) into linear motion (movement in a straight line). These mechanisms can be found in car engines ...

[2n2r5] posted up a mechanism that we’d never seen before — a threadless ballscrew that turns rotational into linear motion with no backlash. It works by pressing the edge of three bearings ...

Planetary roller screw mechanisms (PRSM) are advanced mechanical systems that convert rotational motion into linear motion, commonly used in applications requiring high load capacity and precision ...
