Manual Linear Stage, Crossed-Roller Bearings, 25.4 mm Travel, M6

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. With the additional mounting area on the 426/436 long-rage stages, crossed-roller bearings are used to provide a higher center load capacity while maintaining smooth travel over the entire 1 or 2 in travel. Actuators are spring supported for minimal backlash and achieve <150 µrad deviation, all of which is verified and assured by Newport’s Interferometric Quality Assurance Facility.

These extended range stages are designed with symmetrical features allowing them to be reconfigured for left- or right-handed operation. This video shows a 426 stage being reconfigured to have the actuator accessible from the opposite side of the stage. A left-handed configuration is recommended when using the stage for vertical translation, and it may also be useful for improving adjustment accessibility in some systems.

Our 426/436 Series stages are easily stacked and may also be combined with our Model 360-90 Slotted Angle Bracket for 3-Axis (XYZ) translation. A non-influencing lock secures travel of each stage. The mounting area features an array of 1/4-20 or M6 tapped holes on either a solid platform, or one with a 2-in. diameter aperture (Models 426A and 436A), which is unobscured over 0.625 in. (16 mm) of travel. This video demonstrates how to assemble a 3-axis (XYZ) manual linear translation system with 3x 426 stages and a 360-90 angle bracket. (Note that a left-handed configuration is recommended for vertical translation.)

These stages are sold without actuators, allowing you to customize the translation for your desired precision. Actuators can be easily and quickly interchanged for any necessary adaptations after installation. Adjustment screws, Vernier micrometers, differential micrometers, and motorized actuators all fit the stainless steel actuator mounts on these stages in either a left- or right-handed configuration.
