Polymer ball bearing application



I hope this finds you well
I am currently working on an underwater submersible project for my school and was wondering how I could incorporate polymer ball bearings for the thrusters, ballast tank pumps , robotic arms and for the torque sensors since polymer ball bearings have self lubrication properties and handle sea water better than stainless steel bearings its my hypothesis that they should have longer life cycles but was wondering the exact place I could install them and how would it look like
