Primatics, Inc. Rotary Positioning Stages PFR225

The Primatics PFR225 offers solutions to your rotary positioning needs. Our innovative drive system creates arc-second repeatability and fast settling times, making the PFR225 ideal for point to point indexing, assembly and optical applications where worm drives dont provide the necessary accuracy, throughput or life. Smart Design The PFR225 features a tensioned, precision, steel reinforced timing belt for its drivetrain. The belt has an AT5 tooth profile with nylon faced teeth, providing exceptional stiffness and smooth tooth engagement. Accuracy and repeatability are enhanced through a ring encoder located on the rotating platen providing output feedback directly on the load. An oversized cross roller bearing supports the platen, delivering high load capacity, excellent rigidity, and long life. All PFR225 performance specifications are verified and a full set of accuracy & repeatability 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.
