Air Bearing Spindles

Air bearing spindles are precision engineered components,
requiring careful maintenance and servicing to guarantee the best

An air bearing spindle is a non-contacting system where a gas
film of pressurized air acts as the lubricant to separate two
surfaces in relative motion.  The use of an air chamber provides
many benefits:
  • Minimal wear since there is no mechanical contact, which
    improves the overall bearing life and ensures rotational
    precision remains constant over time.
  • Extremely high rotational speeds allowed by low shear
  • Reduced vibration and constant bearing stiffness.
  • Extreme radial and axial rotational precision.

Refer to the figure below to see the manufacturing precision
required to create the air chamber.

The allowable tolerance for components to meet original design
specifications can be as small .00005”.  Therefore the use of
non-original parts not manufactured to the
exact design
specifications and tolerances can easily effect the product quality
and output.  

At ADS our objective is to repair spindles to perform to original
design specifications and to the highest quality to give accurate,
long performance.  We believe this can only be accomplished
through the use of genuine parts and with limited selective
refurbishment performed by experienced engineers familiar with
Westwind products and standards.
