GPC0805 precision ground micro ball screw is an ultra-compact transmission component designed for high-precision micro devices, with a nominal diameter of 8mm, a lead of 5mm, and a compact size, suitable for space-demanding scenarios.
Using nano-level grinding technology and high-strength alloy steel material, carburizing quenching and surface coating (such as DLC coating) treatment, it achieves ±0.01mm level repeat positioning accuracy (C3/C5 level), backlash ≤0.003mm, and excellent rigidity and wear resistance.
The single nut preload anti-backlash structure is combined with the end cover ball circulation system, with a rated dynamic load of 3~5kN, a maximum speed of 4000~5000rpm, and supports a wide temperature environment of -30°C to 120°C, with excellent impact and corrosion resistance.
Lightweight design (total weight of about 200~300g) and low friction optimization ensure low noise, low energy consumption and high response speed. It is suitable for micron-level precision positioning of precision medical equipment (such as microsurgical instruments), optical focusing systems, semiconductor packaging equipment, micro-robotic arms and high-resolution 3D printers.
The selection needs to match the load and dynamic performance requirements. Regular micro-lubrication and calibration maintenance are recommended. The core advantages are ultra-precision, miniaturization and high reliability. It is the core transmission solution in the field of micro-electromechanical systems and high-end automation (specific parameters are subject to the manufacturer’s technical manual).
