The NRC Newport 435A Linear Transition Stage is a precision positioning device designed for applications requiring accurate linear motion control. Featuring a low-profile design, this stage utilizes crossed-roller bearings to ensure smooth and repeatable movement with minimal friction.
The 435A model is equipped with a Starrett micrometer, providing precise manual adjustments for fine-tuning positioning tasks. Its robust construction allows for a substantial load capacity, making it suitable for various industrial and laboratory applications.
The stage’s platform measures 3.5 inches by 3.5 inches, offering ample space for mounting components. The crossed-roller bearings provide high load capacity over longer travel ranges, ensuring 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. Actuators are spring-supported for minimal backlash and achieve less than 150 µrad deviation.
The 435A stage is designed with symmetrical features, allowing it to be reconfigured for left- or right-handed operation. This flexibility is beneficial for vertical translation applications and can improve adjustment accessibility in various systems.
For multi-axis configurations, the 435A stages can be easily stacked and combined with Newport’s Model 360-90 Slotted Angle Bracket for 3-Axis (XYZ) translation. A non-influencing lock secures travel of each stage, and the mounting area features an array of 1/4-20 or M6 tapped holes on either a solid platform or one with a 2-inch diameter aperture, which remains unobscured over 0.625 inches (16 mm) of travel.
The 435A stage is compatible with various manual or motorized actuators, allowing customization of the translation for desired precision. Actuators can be easily and quickly interchanged for 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.
In summary, the NRC Newport 435A Linear Transition Stage offers a reliable and versatile solution for precise linear positioning needs, combining high load capacity, smooth motion, and adaptable configurations to meet diverse application requirements.
