API50 Crossed Roller Bearing Stage
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.
