Latest High Precision Air Bearing Linear Positioning Tool by H2W

H2W introduces its latest high precision air bearing linear positioning stage (ABS-012-12-030-X).

The ABS series stage incorporates five magnetically preloaded air bearings for both load carrying and lateral guidance. The base of stage is constructed using a lapped granite surface plate and the lateral guidance is controlled by a granite straight edge that is mounted to the base.

The non-contact 3 phase brushless linear motor operates in conjunction with a high resolution linear encoder for closed loop operation.  The ironless core coil assembly has no magnetic attractive force to the stationary magnet assembly, and as a result it does not induce any cogging into the system.  The lower moving mass of the stage allows for much higher accelerations of light payloads.

The stage has a stroke of 12 in [300 mm]; generates 20 lbs [89 N] of continuous force and 60 lbs [267 N] of peak force.  It includes a 1 micron resolution linear encoder.  

H2W’s line of air bearing positioning stages are ideal for high precision applications requiring extremely flat and straight,  non-contact motion.    


  • Non-contact air bearing operation

  • Excellent flatness and straightness specifications

  • Lowest velocity ripple

  • No wearing parts

  • Custom strokes and force configurations available.

H2W Technologies is dedicated to the design and manufacture of linear and rotary motion products that are used in the motion control industry.  The complete line of linear electric motors includes: single and dual axis linear steppers, DC brush and brushless linear motors, voice coil actuators, and AC induction motors.  Also offered is a complete line of ball screw, lead screw and belt driven positioning stages.

Other motion control products include: limited angle torque motors for compact, limited angular excursion rotary servo applications, 3 phase brushless rotary servo motors with matching digital servo amplifiers and permanent magnet linear brakes for fail-safe, zero power braking for baggage handling and people moving applications as well as amusement park rides.

With over 75 years combined experience in the linear and rotary motion field, the H2W Technologies team of engineers offers the optimal solution to the most demanding motion control requirements.
