Product Detail

Models 423, 433, and 443 feature exceptional performance, usability, and value with precision ball bearing construction – hardened balls rolling between opposing pairs of hardened and polished stainless steel rods. For stability, repeatability, and exceptionally smooth motion, actuators bear upon a hardened carbide insert. Springs provide preload against the actuator tip to eliminate backlash.

A stable stainless steel actuator mounting system allows your choice of manual or motorized actuators to be attached in either a left or right-hand configuration. A non-influencing lock (also reversible for left-handed configuration) similar to that used on our top-of-the-line ULTRAlign™ Series Stages provides positive stable positioning and guards against inadvertent adjustments. For higher load capacity, see 426 and 436 Series Crossed-Roller Low-Profile Stages, or our Double-Row Ball Bearing UMR Series Stages.


Preloaded precision ball bearing movements provide reduced friction and capability to make small controlled movements. Bearings are captured in hardened steel rod guides.


Order actuators separately. 443 is shown with SM-50. 443-4 requires two SM-50s.


OEM versions available.


Models 360-90 and 360-30 can be used to make long-travel XYZ stages using linear stages like our Models 423, 433, 443, 426, or 436.


Extra actuator mounting block, AB-3.


Extra actuator push block, AB-4.
