NSK Nakanishi ABT-1000 Air Bearing Spindle - 100k RPM


NSK Nakanishi ABT-1000 Air Bearing Spindle - 100k RPM

Availability: In Stock
Product SKU: ABT-1000

The NSK Nakanishi ABT-1000 is an Air Bearing spindle that can run up to 100,000 RPM with an output of 88W. Ideal for extremely high precision, small diameter machining applications.

Air bearings use compressed air blown into a small gap between the spindle and the bearing surface. 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.
