NSK MSS-25 Series Air Spindle

This NSK MSS-25 Series Air Motor Spindle incorporates a specially designed 24,000 rpm air motor.  The {6,000 and 1,500 min (rpm)} versions also utilize a high-precision small planetary gear speed reducer system which provides high torque, high outpower and excellent durability. 6,000 min (rpm): 1/4 motor speed reduction, Torque is 4 times greater than the motor torque. 1,500 min (rpm): 1/16 motor speed reduction, Torque is 16 times greater than the motor torque. The NSK MSS-25 series motor spindle is designed to be mounted in a ø1.0" (ø25.4mm) holder.  This greatly extends the capabilities of existing NC and CNC lathes and also makes them very easy to incorporate in the design of special purpose machinery.
