Back in the 1980s, Pacific Bearing Co. (PBC) invented and commercialized plain bearings, which were sized to be interchangeable with linear ball bearings. Plain bearings worked very well in certain ...

Linear bearings are distinguished from radial bearings by their sliding rather than rotary motion. Linear bearings are used in machine tool applications such as sliding doors, 3D printers, and ...

When in doubt, make it stout. That was the rule of thumb for designing strong and durable machine tools in the past. Over the years, however, this mindset has changed as technical advances have ...

Rotary Air Bearings provide High Precision Motion with Minimal Eccentricity and Wobble. The rotary air bearing on the left is non motorized – its low friction is apparent from the long time it keeps ...
