Model 426 and 436 Series High-Performance Low-Profile Crossed-Roller Bearing Linear Stages feature crossed-roller bearings running on ground steel V-ways to provide an attractive combination of high-resolution movement, low runout, and large load capacity. For stability, repeatability, and exceptionally smooth motion, actuators bear upon a hardened carbide insert. Springs provide preload against the actuator tip to eliminate backlash. To ensure consistently dependable performance, these stages are extensively tested in Newport’s Interferometric Quality Assurance Facility.
A highly stable and rigid stainless steel actuator mounting system allows your choice of Newport’s manual or motorized actuators to be attached to the stage in either a left- or right-hand configuration. A non-influencing lock (also reversible for left handed configurations) similar to those used on our top of the line ULTRAlign™ Series provides positive stable positioning and guards against inadvertent adjustments.
Solid platform and aperture platform versions are offered. Each features a convenient array of 1/4-20 or Metric M6 tapped holes. The 2 in. diameter apertures of Models 426A and 436A are unobscured over 0.625 in. (16 mm) of travel. The stages are easily stacked for XY applications, and may be combined with our Model 360-90 Angle Bracket for XYZ configurations.
