Linear motors are the most expensive, followed by screw-type actuators (planetary screw, ball screw, and lead screw). Belt drives are the most economical. Engineering always involves trade-offs.

An example of a tubular linear actuator is the Model STA 11, which provides a 14-to-232-mm stroke. Thrust-rod diameter is 11 mm. Peak force is 92 N, and maximum velocity is 4.7 m/sec.

BARTLETT, Ill., July 10, 2017 /PRNewswire/ -- As part of its cyber dynamic line product series, WITTENSTEIN cyber motor has launched a new series of linear actuators designed with an integrated ...

For tasks requiring sub-micrometer precision — such as alignment, adjustment, or fine positioning — PI’s M-235, L-220, and ...

Linear actuators are particularly hard to make cheap, ... The last gear in the train is tasked with turning a lead screw which drives the arm of the linear actuator back and forward.

As the screw moves in and out of the actuator, the magnet moves toward and away from the sensor face causing the device to switch states. The proximity sensor is designed to operate in a digital ...

The SLME is a ball screw-driven linear actuator that uses a fine-pitch ball screw and recirculating ball bearing guide designed to achieve high accuracy and repeatability. The ball tracks of the SLME ...

For all but the very highest force requirements, electric servo presses provide numerous advantages over their historic, ...

It’s these mechanisms that [Nemo404] has taken a little further, freeing the lead screw and motor from the drive chassis and placing them in a 3D-printed enclosure for a complete linear actuator ...

Actuators—described as “the crown jewel of the core moving parts of robots”—convert rotary motion into linear motion, a crucial function for robotics and especially for humanoid robots ...
