While we normally don’t make it a habit to feature Kickstarter projects, we couldn’t pass this one up. [Barton Dring] from BuildLog.net is putting together a project called MakerSlide that we’re sure ...

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 ...

The amount of preload applied can be used to adjust the stiffness (and friction) of the bearing by changing the ball size to as small as 1 µm. Each application is a little bit different. For every ...

• Direct-drive brushless linear servo motors with alternative feedback technologies and both linear motion guide or air bearing technologies provide the basis for wide choice of solutions for long ...

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 ...

For the benefit of our readers, what is the principle of Aerostatic bearings, and how do they compare to roller-element or oil hydrostatic bearings? There are two types of aerostatic bearings, inlet ...
