WebA ball screw works in a similar way to a conventional lead screw, but the significant advantage of using a ball screw is that it uses ball bearings running in the helical channel to transmit the load. In high precision applications it is often necessary to translate the rotary motion from a motor to linear motion for the payload.
WebScrews change a gentle turning force into a strong forwards force. They do this with a spiral pattern called a “thread”, which runs round and round the screw from the wide top to the narrow end. Each time the screw is turned, the thread pulls it a short distance along. The force required to move the screw forward is spread out all along the ...
