Festo has introduced its newest generation of Cartesian handling system mechanical axes: ELGD-TB tooth belt actuators and ELGD-BS ball screw actuators.These actuators feature bearings inlaid into the ...

Ocean Harvesting and ball screw manufacturer NSK have completed the design of the ball screw actuation system for InfinityWEC generation 6, and Ocean Harvesting is now raising 500 000 EUR for 2024 ...

Specifying a Linear Actuator: 3 Key Factors November 17, 2021 by Mark Allinson Leave a Comment By Japh Humphries , UK Sales & Co ...

Traditionally, ball screws—which feed a series of balls through a screw shaft and nut—have been the primary type used in robotics. But a new component is set to supercharge humanoid motion and ...

“Humanoids, such as Tesla Optimus, mainly use ball screws and planetary roller screws for linear actuators to perform high precision motions,” highlighted the research paper.

Planetary roller screws are emerging as a critical—and costly—component in next-gen robots. China is racing ahead in controlling their supply.
