Ball screw

Ball screw

Ball screw

(OP)
I am looking for ballscrew which equipped with controllable linear clutch to control engaging/disengaging of the ballscrew's nut. Therefore, when this nut is disengaged, the nut can move freely under the external load without any effect on the ballscrew. And when the nut is engaged, the ballscrew will move the nut up or down according to the rotation direction. Does anyone have an idea?

Linear motor?

RE: Ball screw

(OP)
Linear drive nut is manually controlled via lever to switch between engage and disengage. Is there an electrical controlled one instead of the manual one?

RE: Ball screw

The Uhing product can be pneumatically actuated. Not sure if there is a purely electrical version. Probably need a good deal of force.

Rohlix has a lighter duty version with manual quick disconnect. You could re-engineer using an electro-magnet.
