Hello .
My turner friends made this module for me.
I don't know what's inside this bearing block, I haven't disassembled it. The air goes through the shaft from the clamping sleeve side and flies out through the threaded hole [from the top of the housing] in the module housing and the air is sucked in by the vacuum pump. The device is filled with oil and sealed. The shaft rotates very easily and without play in the sliding bushes.
From the bottom, the shaft should be driven by a direct drive motor. If I have time, I will make a video of the principle of operation of this bearing block.
