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 ...

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 ...
