Ace Glass 8125-08 Stirring Shaft Coupling, 10mm, 5/16" O.D.

Features:

• Couples stir motor shaft to reactor stir shaft. Flexible neoprene rubber body with PTFE sleeve inside corrosion-resistant metal end that provides angular and parallel misalignment of glass or metal stirring shaft without danger of breakage.
• Rubber body absorbs shock and provides quiet vibration free running with great torsional stiffness.
• Measures four inches overall.
• Easy to Use:
  • Slip coupling end with PTFE sleeve over stirring shaft as far as it will go, approximately three inches.
  • Bring motor shaft down and align visually approximately 1/2 inch above coupling and shaft. Secure motor position and recheck alignment.
  • After motor and reactor are securely in place, slide coupling over motor shaft and tighten set screw.
  • Slide stirring shaft up into coupling just enough to clear bottom of reactor.
  • Tighten PTFE sleeve over shaft, using brass set screw, just enough to prevent slippage.
