Ace Glass 8051-15 10 mm Shaft, 29/42 High Speed Vacuum Trubore Bearing

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 1000 rpm 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 precision ground, 10 mm stirring shaft.
