Brass bearing base suitable for TD124

Teflon shock-absorbing pads. Fluorine rubber sealing ring.

CNC precision machining.

I recommend using the silicone gasket I provided for sealing instead of the additional paper pad. Because the thickness of the outer wall of this bearing sleeve is limited, after being occupied by the 3MM screws, the area available for sealing is very limited. Using the silicone gasket is a better choice. Of course, this is just my suggestion. The final decision on how to proceed is up to you.
