S225A The model has been changed to a new design with excellent durability and practicality. By adopting a new frame and high-performance iron core, it is lighter and more compact than the previous model, so as to reducing heat generation. A drill chuck or boring unit can be attached to the shaft end for drilling. In addition to the standard Jacob taper, a straight type is also available. Type S225A Output power 0.4kW Poles 2P Voltage 200V Frequency 50/60Hz Max.rpm 3,000/3,600rpm Spindle nose Jacob stapler No.6 Cooling Fully closed Distortion 0.01mm or less Vibration V5 (Amplitude 5μm or less) S225B By using a silent fan and special bearings, vibration and noise are reduced; cooling efficiency is improved, and heat generation is reduced. For the shaft end, we can also make special shafts with double shaft type and highly precise specifications.
