TH35 160 Precision Rotary Stage

Direct Drive Rotary Stage

The TH35 160 is a high precision direct drive rotary positioning stage. Stiff, high precision cross roller bearings give the rigidity needed for backlash-free positioning, while a high resolution absolute multi-turn rotary encoder delivers calibrated accuracy to ±2.5 arc seconds. Endless rotation at speeds up to 1500 rpm makes it equally suited to indexing and continuous rotary motion.

Direct Drive Torque Motor

Direct drive torque motors remove the need for a gearbox or transmission. The rotor is attached directly to the driven part, eliminating backlash, transmission losses and the cost and maintenance of extra components. With no contact between rotor and stator there is no mechanical wear, giving smooth, efficient motion and a long service life.

Applications for Rotary Stages

Precision rotary stages are used wherever accurate angular positioning is required, including optics and laser systems, precision manufacturing, metrology and inspection, robotics, aerospace, medical devices and research laboratories. The TH35 160 can also be combined with linear stages to build multi-axis systems.
