Using nano-level grinding technology and high-hardness alloy steel material, carburizing quenching and DLC (diamond-like carbon) coating strengthening treatment, it achieves ultra-high repeat positioning accuracy of ±0.003mm (C3 level), backlash ≤0.002mm, and industry-leading rigidity and wear resistance.
The single nut preload anti-backlash structure is combined with a micro-end cap ball circulation system, with a rated dynamic load of 4~7kN, a maximum speed of 7000~9000rpm, and supports extreme temperature ranges from -40°C to 150°C, and is compatible with complex environments such as vacuum and high humidity.
Lightweight design (total weight of about 0.8~1.2kg) and low friction optimization ensure high-frequency response, ultra-low noise and ultra-long life. It is suitable for semiconductor lithography machine precision stage, super-resolution microscopy system, spacecraft attitude adjustment mechanism, gene editing equipment micro-operation platform and laser interferometer nano-level displacement control.
The selection must strictly match the dynamic load and acceleration curve, and special lubrication solutions and regular calibration are recommended. The core advantages are sub-micron accuracy, maximum speed and adaptability to extreme environments. It is the core transmission unit for cutting-edge scientific research and ultra-precision industrial equipment (parameters are subject to the manufacturer’s technical manual).
