Description
The TBRK Series Motorized Rotation Stage is a high-precision rotary positioning platform designed for demanding applications in automated alignment, inspection, and multi-axis motion systems. Available in two models—TBRK100 (Φ102 mm) and TBRK200 (Φ196 mm)—this series offers smooth, accurate 360° rotation using a cross-roller guide mechanism and worm gear transmission (180:1 ratio) for enhanced rigidity and repeatability.
Both stages support stepper or AC servo motors with encoder feedback for closed-loop or open-loop operation. They offer sub-millidegree resolution (up to 0.0005°) and repeatability of ±0.003°, making them ideal for high-precision tasks. Each unit includes either a built-in zero sensor or an optional external limit sensor for angular positioning control.
With high load capacities (up to 40 kg horizontally), robust construction, and compatibility with 2D/3D multi-axis systems, the TBRK series excels in optical metrology, semiconductor processing, photonics, and more. Choose the TBRK stage that fits your space, payload, and precision requirements.
