Gas-Purged Bearing Assembly

This gas-purged bearing assembly is designed to fit snugly into the 24/25 center port found on most Pine Research electrochemical cells.  The bearing has a 15.0 mm ID hole through which a 15.0 mm OD shaft can be inserted down into the cell.

The bearing assembly also has a small port on the side so that the internal space within the bearing can be purged using a positive pressure of inert gas flowing into the port.  The tapered outer body of the bearing assembly is fabricated from chemically-resistant PEEK.  The bearing itself is ceramic and is also resistant to chemical attack.
