NB8 Linear Stage

The NB8 high capacity precision linear stage is designed for a variety of applications in research and other industrial areas requiring precision positioning such as in semiconductor processing, fiber optics manufacturing and biotech automation.

The design of the NB8 Series linear stages was optimized for maximum stability and performance with the use of FEA analysis and incorporates the best in materials and component selection. The drive system utilizes a 12mm diameter ball screw with a 4 mm lead.  The use of 15 mm recirculating ball bearing linear guides provide a smooth motion with high load capacity and stiffness. Since the carriage is supported over the entire travel of the stage, a high cantilevered load capacity can be achieved. Separate connectors for motor power and limit/encoder signals are provided for ease of operation. Integrated limit switches and a high torque size 23 stepper motor are supplied as standard items.

An extended temperature range version is available (-50° to 70°C).
