The Primatics PCR43 Series positioning stages are the most vertically compact of our linear stages. The PCR43 is ideal for high precision alignment and attachment, offering unparalleled flexibility—our compact design allows the user to fit a standard product into their most space-constrained applications.


Alignment applications require high resolution and step accuracy for optimal performance—the PCR43 employs a center-driven, brushless linear motor and an internal 20 nanometer resolution glass scale, linear encoder specifically for this purpose. All the multiplication electronics are internal to the PCR43, eliminating large external electronics and simplifying cable management. The PCR43 can also be utilized in vertical applications using an optional counter-balance system.

All PCR43 performance specifications are verified with a laser interferometer system, and a full set of accuracy, repeatability, straightness and flatness plots are included with each stage. Additionally, each unit undergoes extensive burn-in and testing—these steps ensure that the stage will deliver optimal performance over a long period of time.
