Model 426/436 Series Extended Platform Crossed-Roller Bearing Stages feature extra large solid and apertured platforms complemented by 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, every stage is 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) 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.

Preloaded crossed-roller bearings provide repeatable, zero stick-slip linear motion with negligible side-play. The roller strips hold cylindrical rollers alternately inclined 90° to assure constant linear contact with the hardened and ground ways.
Model 426A is shown with SM-25 ordered separately.
Use an angle bracket to create multi-axis assemblies.
