  • Air Bearing Benefits - Westwind Air Bearing Spindles

    Air bearings have low fractional drag, permitting high speed whilst retaining very low vibration levels. The frictional resistance to rotation of an air bearing is very small and, subsequently, the loss of power and heat generation is also very small. This allows the shaft to be run at very high surface speeds.
