Ace Glass, Inc. Bearing, Trubore, glass, 10mm, 35/20, 35/25
10mm Trubore glass bearing with 35/20, 35/25 spherical joint. Bearing is for use with aluminum packing box in low positive pressure and vacuum applications. Using the graphite-impregnated PTFE packing and ACE Stir-Lube, pressures down to 7 microns have been obtained at 170rpm, using only a mechanical pump. Speeds over 1000rpm are not advisable due to heat generated. Indefinite packing life. Frequent tightening of the packing box is unnecessary once the packing has run in. The high vacuum lubricant trap adapter prevents lubricant from running into stirred material. Use with precision ground, 10mm stirring shaft.
Ace Glass, Inc. Bearing, Trubore, glass, 10mm, 34/45
10mm Trubore glass bearing with 34/45 standard taper joint. Bearing is for use with aluminum packing box in low positive pressure and vacuum applications. Using the graphite-impregnated PTFE packing and ACE Stir-Lube, pressures down to 7 microns have been obtained at 170rpm, using only a mechanical pump. Speeds over 1000rpm are not advisable due to heat generated. Indefinite packing life. Frequent tightening of the packing box is unnecessary once the packing has run in. The high vacuum lubricant trap adapter prevents lubricant from running into stirred material. Use with precision ground, 10mm stirring shaft.
Chemglass Life Sciences Chemglass 29/42 Lower Joint Adapter for 10 mm Stir Shaft - Mechanical seal bearing, 1-3/4 in threaded connection (CG-2077-M-38)
Lower joint adapter for 29/42 ground joints that provides a dry-running mechanical seal for 10 mm stir shafts and a 1-3/4 in threaded connection. Supplied complete with perfluorinated O-rings and a loosening nut, the adapter resists aggressive chemicals while minimizing contamination and allowing vertical adjustment for different agitator styles.
- Provides a vacuum- and pressure-tight seal for 29/42 lower joints.
- Designed for 10 mm stir shafts and 1-3/4 in threaded connections.
- Includes perfluorinated O-rings and a loosening nut for chemical resistance.
- Dry-running mechanical seal rotates with the shaft to prevent contamination.
- Rated to 5 Torr vacuum and 2-3 psi pressure; seals up to 2000 rpm.
- Compatible with glass, metal, or PTFE-covered stir shafts and allows vertical adjustment.

Chemglass Life Sciences 10mm Chem-Vac Stirrer Bearing, PEEK/PTFE Stabilizer, PTFE, 29/42 Joint Size
10mm Chem-Vac Stirrer Bearing, PEEK/PTFE Stabilizer, PTFE, 29/42 Joint Size. 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.
Chemglass Life Sciences Stirrer Bearing, PTFE, Complete, fits 10mm Shaft, 45/50 Inner Joint
Stirrer Bearing, PTFE, Complete, fits 10mm 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. PLEASE NOTE: FOR USE ONLY WITH CG-2078 OR CG-2079 PRECISION GROUND AND POLISHED STIRRER SHAFTS.
