Machines that turn, eject, cut, and spray rely on efficient, automatically reversing linear motion. Rolling-ring linear drives are commonly used in these types of applications because they eliminate ...

Rolling-ring drives are friction drives that convert the constant rotary motion of a plain shaft into a traversing action that moves an attached carriage. Used in positioning and reciprocating ...

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, printing ...
