Those are what some folks would call a lazy susan. I've also seen them called turntables. In essence, it's a very large-diameter ball bearing. Similar to what you circled earlier, only much flatter.

What is the larger "Case" or shaft around the smaller shaft that powers the wheel?

Most folks would call that a sleeve, and it's a second shaft that rotates the wheel.

BTW, there are more types of swerve modules than coaxial, if you wanted to try to locate some pictures. 3928 did some last year where the motor was inside the wheel; I think 16 has done some where the motor is in the module.
