Precise movements are made with precision slides. Reciprocating linear bearing accuracy, the possible runout in any plane, is typically as low as 0.005 in./in. Because linear bearings are only as ...

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 ...
