To get the most out of ball screws, they must be protected from coolants and debris. Today’s machines tools routinely operate on a 24/7 basis with little, if any, downtime allowed for routine ...

Ball screws and roller screws are widely used for high-force linear motion and are replacing fluid power devices. In general, these screw mechanisms generate linear motion by rotating either the screw ...

Ball screw mechanisms represent a critical class of precision drive components that convert rotational motion into linear motion by utilising recirculating ball bearings. This conversion is achieved ...

MACHINE FEED DRIVES that use ball screws that incorporate rotary encoders are prone to position measurement error as a result of thermally induced expansion because ...

Most inexpensive 3D printers use a type of lead screw to move some part of the printer in the vertical direction. A motor turns a threaded rod and that causes a nut to go up or down. The printer part ...

Translating rotary motion to linear motion is a basic part of mechatronic design. Take a look at the nearest 3D-printer or CNC router — at least the Cartesian variety — and you’ll see some mechanism ...
