The spindle floats on an even cushion of compressed air. This non-contact type of bearing means the spindle has a very long service life because of low friction and wear ; it also means that the spindle generates almost no heat or vibration. • The spindle and bearing are finished with a very high-accuracy process to ensure extremely low vibration and very high rotating accuracy. • The ABT Series are equipped with a Rotational Speed Detection Sensor. When in operation, a digital pulse signal representing the RPM can be output. The rotation speed and load condition can be monitored using a high performance, locally available speed meter. ABT Series Connection Drawing The ABT Series motor and spindle require dry, clean, regulated air. Please refer to the drawing for proper components.
