Air Bearing Spindles

With the advent of CNC technology, machine tools are expected to be more accurate, efficient, and reliable than ever. To remain competitive, machining companies are investing in high quality bearings that ensure top equipment performance. The overall purpose of a spindle bearing is to enhance and streamline spindle movement to ensure optimal machine speed and accuracy. Bearings affect the speed, rotation, vibration, precision, and temperature of the machine tool, which in turn alters the quality of the final product. 

Bearings are typically composed of a ring or series of rings with a ball or other rolling element that streamlines the motion of the spindle in the desired direction. Depending on the equipment and desired motion, bearings can be engineered to facilitate the movement of spindles on both lateral and radial axes. They must be able to withstand the load pressure, temperature, and high speed of machine tool spindles.
