Machines that turn, eject, cut, and spray rely on efficient, automatically reversing linear motion. Rolling-ring linear drives are commonly used in these types of applications because they eliminate ...

Ball splines and bearings: each play a role in mechanical function, and each are unique. All types of machinery are provided with supports for rotating shafts, and that supporting device is a ...

Frictionless Bearing Design, Lock-Down Mechanism for Ultra-High Stability With its frictionless air bearings and non-contact motors, the A-361 ensures smooth motion without wear, enabling virtually ...

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 ...

Integrating sensors into rotational mechanisms could make it possible for engineers to build smart hinges that know when a door has been opened, or gears inside a motor that tell a mechanic how fast ...
