Print Datasheet


The OFL™ series of motorized XY stages and linear slides employs individually preloaded ball way construction and avoids the difficulties inherent in establishing a preload across the table’s open plates. This design also places the lower axis motor on the base plate to remain stationary while the upper axis motor moves in only one direction.

The aperture sizes available range from 240 to 675 millimeters with a total unobstructed area of 42-by-42 millimeters. Side-mounted lead screws with anti-backlash friction nuts are driven by 23-frame motors. The OFL™ motorized XY stage has a larger frame size motor with more torque compared to the XYMR™ and OFS™ series.

Design Features

  • Clear aperture for two-sided access
  • Large 42 millimeter unobstructed opening


  • Motor options available: stepper motors or servo motors
  • Feedback options available: rotary encoder, linear encoder with analog or digital (1 um or 0.1 um resolution are standard, other resolutions available upon request)
  • Download the datasheet for this linear motion XY stage for additional technical details
