NEW Chem-Vac™ PTFE stirrer bearing provides a VACUUM TIGHT FLAKE-FREE SEAL. Two versions of the bearing are available, the standard series for 2L and smaller vessel capacities and the stabilizer series that incorporates a PEEK®/PTFE stabilizing bushing that is molded to the lower portion of the inner joint. The stabilizer greatly reduces stirrer shaft whip on larger vessels. The bearing consists of a PTFE standard taper body, Glass filled polypropylene screw cap, PEEK® Compression spring, PEEK®/PTFE sleeve and a glass filled polypropylene loosening nut. The polymer blend sleeve provides a long-lasting seal for use up to 500 RPM. Loosening nut above the standard taper inner joint allows easy and quick removal. PLEASE NOTE: PTFE STIRRER SHAFTS ARE NOT RECOMMENDED FOR USE WITH THIS BEARING.
