The Primatics PCR32 Series positioning stages are the most compact of our linear stages. The PCR32 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.
The PCR32 delivers exceptionally smooth travel by utilizing anti-cage creep, precision cross roller bearings, and a center-driven, brushless linear motor. Since neither the bearings nor the drivetrain utilize recirculating elements the PCR32 offers the best of everything—smooth velocity, ripple-free motion without cage creep
The PCR32’s oversized cross rollers and a re-enforced linear motor forcer yield a positioning stage with a very high natural frequency—this high bandwidth allows the PCR32 to step and settle very quickly, making it ideal for applications where the stage must keep a camera in focus while following a terrain.
The Primatics PCR32 Series is designed specifically for high throughput, continuous applications—the cross rollers are preloaded against machined reference edges to insure no loss of preload over time.
All PCR32 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.
