Here is a sample design for a turret bearing* constructed using the Elevator Bearing Kit V3.
The inner and outer plates can be fabricated from any desired material. Aluminum is preferrred, but wood or plastic could be functional in the right application. The plates could be laser cut, water jetted, or CNC milled/routed.
The design can be scaled to any diameter and more or less roller blocks can be used depending on the amount of support required.
*This mechanism is intended as an example to help inspire teams to come up with designs of their own. It is not guaranteed to be capable of completing the described task or being legal under the 2020 FRC rules.
