Our unique, tangential drive system uses a precision grade ball screw, providing an alternative to worm drivetrains that can wear prematurely and develop backlash—this solution ensures high stage durability and long life. The low friction of a ball , screw drivetrain delivers significantly less backlash than a worm drive, ensuring quality performance for millions of cycles, even in high speed, high acceleration applications.

All PLR350 performance specifications are verified, and a full set of accuracy and 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.
