Stirrer Bearing, PTFE, Complete, fits 10mm Shaft, 34/45 Inner Joint. Grease-Free PTFE stirrer bearing designed for use in moderate vacuum applications. Bearing consists of a threaded glass adapter having the listed inner joint, a saddle o-ring, a body bushing with a compression and locking nut, and a precision PTFE inner bearing. The saddle o-ring provides only glass and PTFE contact with the reaction, while allowing for the vacuum tight seal. Design of the bearing permits replacement of the saddle o-ring at a fraction of the cost of the entire bearing. PLEASE NOTE: FOR USE ONLY WITH CG-2078 OR CG-2079 PRECISION GROUND AND POLISHED STIRRER SHAFTS. Made in the United States.
