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 ...

A few simple tips for maintaining accurate, reliable ball screws. It's relatively simple to determine the lead accuracy of a ball screw before you buy it. Just ask the manufacturer and get a protocol.

With so many different ball screws on the market and the attendant flood of data from manufacturers, designers can have a tough time sorting out what truly affects ball-screw performance. Information ...

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 ...

Super smooth: the updated linear-shift mechanism from UHV Design exploits a precision slideway to increase the translation speed (Courtesy: UHV Design) UHV Design, which specializes in the design, ...

A lot of the projects we feature here on Hackaday engender the classic “build versus buy” argument. We’ve always been puzzled by that; if anyone can appreciate the sheer joy of making something rather ...

The PRS models, with G5 lead accuracy, are available in screw diameters ranging from 8- to 80-mm, and deliver static load ratings up to 218,000-lbf. Exlar’s PRR models, with G9 lead accuracy, are ...
