Squares iSpeed5


60,000-80,000 Max RPM, 350W


  • Fully tool-changeable electric spindles increase machine tool speed.
  • The iSpeed5 System primarily consists of a motor spindle, stop block, air pressure switch and control unit. Power, cooling air, and control signals are provided to the spindle when engaged to the innovative electromechanical stop block that attaches to your machine tool spindle.
  • The iSpeed5 is created for continuous lights out manufacturing even in the case of cutting fluids and coolants.
  • The internal air passage allows the pressurization and cooling of the system while preventing the entry of contaminants into the stop block. 

Please contact NSK America Corporation directly for information regarding iSpeed5 for your machine.
