Rotary Nut lead screw, input requested

The bearings inside the ballscrew assembly are my main focus. Surely they’re running a tapered bearing in there. They really don’t have many close up pictures of their design.

The ball nut is the outer bearing race and the ball shaft is the inner bearing race.

Right, I understand how a ball screw works. But there is a bearing that allows the ball nut to rotate. The part that the nut is attached to. It lets the nut rotate and provide linear movement. Their design is much slimmer than the other options on the market. I’m curious how they have the bearing and housing designed to eliminate preload. Wondering if it’s a collection of off the shelf parts or if it’s custom made for them.

This is what most other driven nut systems look like
