ERG-HP High-Precision Electric Rotary Gripper
Equipped with a high-precision direct-drive motor and encoder, it delivers ±0.005° rotary repeatability and 0.001° position resolution. Designed for ultra-precision rotary applications such as semiconductor wafer alignment, optical lens focusing, and rotary positioning of precision electronic components.
The Expert in Ultra-Precision Rotary Positioning
The ERG-HP high-precision electric rotary gripper uses a frameless torque motor in a direct-drive design that eliminates transmission backlash. Paired with a high-resolution absolute encoder, it achieves ultra-precision rotary positioning, with rotary-end runout controlled at the micrometer level to meet the demanding requirements of optics, semiconductor and related industries.
The gripping side features micro force-control technology with a minimum grip force of 1N and 0.05N force resolution, safely handling delicate precision parts such as optical lenses, wafers and chips. Cleanroom-compatible (ISO Class 5), it is ideal for high-end manufacturing in semiconductor, optics and precision instruments.
