Rolling-ring drives are friction drives that convert the constant rotary motion of a plain shaft into a traversing action that moves an attached carriage. Used in positioning and reciprocating ...

PI, a global leader in precision motion control and nanopositioning, offers a broad range of piezo ceramic linear actuators ...

Armed with even with the most-sophisticated motion controller, engineers can still find it difficult to attain precise linear motion unless the mechanical components are appropriately designed for the ...

Stepper motor linear actuators (SMLAs) combine a stepper motor, precision lead screw and nut in one compact envelope, providing a highly configurable, customizable and robust system for linear motion.

RC servos are handy when you need to rotate something. You can even modify them to rotate continuously if that’s what you need. However, [Roger Rabbit] needed linear motion, but wanted the simple ...

A cam is a rotating piece that converts rotary motion into reciprocating motion in the follower. Think of it like a spinning shape pushing something up and down. Eccentric/off centre cam: this is the ...

Monitoring takes the form of sensors and intelligent devices connected to a digital processor. These monitored values are used for computing and then controlling some sort of real-world action. Many ...

Breaking with traditional linear actuator principles - advantages for nanopositioning in optics, astronomy, aerospace, ...
