Air bearing spindles are often found in the precision rotary fixture industries. They are frequently very high speed and high precision spindles used for light load capacity and minimal stock removal for drilling, milling, dicing, grinding, and routing applications. Rebuilding an air bearing spindle can be very difficult.
