Chemglass CG-2077-05 Stirrer Bearing PTFE Complete 45/50 Inner Joint

Chemglass, CG-2077-05, Stirrer Bearing PTFE Complete Fits 10 mm Shaft 45/50 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.
