PLR350

Primatics PLR350 Series rotary positioning tables offer a variety of options for systems in need of small, stiff angular corrections. An innovative drive system creates arc-second accuracy and fast settling times, making the PLR350 ideal for point to point indexing, assembly and optical applications where worm drives don't provide the necessary accuracy, throughput or life.

Durable Drivetrain

Unlike worm drivetrains that can wear prematurely and develop backlash, our unique tangential drive system uses a precision grade ballscrew to ensure high stage durability and long life. The low friction of a ballscrew drivetrain delivers significantly less backlash than a worm drive, ensuring quality performance for millions of cycles, even in high speed, high acceleration applications.

Performance Verification

All PLR350 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.
