API50 Crossed Roller Bearing Stage

The API50 is a mid-range precision, low profile, 3mm crossed roller bearing stage with excellent stiffness and durability.  The high efficiency ball screw drive uses a preloaded nut for good bi-directional repeatability without the use of a linear encoder.  A NEMA17 motor mount accepts stepper, DC servo, or brushless servo motors.  Optical limit and home switches provide protection with long-term reliability.

 
NOTE: If you are looking for tighter specs and tolerances, we can customize to your needs.
