The Primatics PZB25 Series elevator stage offers an ideal solution for applications that require precise vertical motion—the design and components ensure sub-micron resolution in a compact profile and make the PZB25 an ideal solution for semiconductor wafer inspection, fiber optic alignment and assembly, and consumer product inspection and assembly.


Smart Design

The PZB25 utilizes a moving wedge design to achieve vertical motion—the wedge converts the horizontal movement of a precision ball screw into vertical elevation. The high quality, linear bearing system minimizes off-axis motion and assures high reliability and long life. The NEMA 17 motor mount enables the use of stepper or servo motors, including smart motors.


The PZB25 is a higher performance, space-saving alternative to traditional Z-axis stages—the inclined plane approach offers superior performance, through the use of our reliable ball screw drivetrain, while minimizing the overall height. Additionally, the center of the carriage is centered over the bearings, minimizing deflections from cantilevered loads.

Standard Features

An array of integral limit switches and stepper or servo motor options come standard—a clear anodize finish is also standard. Additionally, the PZB25 can be directly stacked with the Primatics PLG160 and PLC65 linear stages and the PDR160 rotary stage.
