GIC0805 precision ground micro ball screw is an ultra-compact transmission component designed for high-precision and high-dynamic response scenarios. It has a nominal diameter of 8mm, a lead of 5mm, and a compact size, suitable for miniaturized equipment with strict space requirements.
Using nano-level grinding technology and high-strength alloy steel material, carburizing quenching and DLC (diamond-like carbon) coating treatment, it achieves ±0.005mm ultra-high repeat positioning accuracy (C3/C5 level), backlash ≤0.003mm, and industry-leading rigidity and wear resistance.
The single nut preload anti-backlash structure is combined with an end cap ball circulation system, with a rated dynamic load of 4~7kN, a maximum speed of 5000~7000rpm, supports extreme temperature ranges from -40°C to 150°C, and is compatible with complex working conditions such as vacuum and high humidity.
Lightweight design (total weight of about 150~250g) and low friction optimization ensure high-frequency response, low noise and ultra-long service life. It is suitable for precision medical equipment (such as minimally invasive surgical robots), semiconductor wafer positioning, aerospace micro-servos, ultra-precision optical platforms and nano-motion control of industrial micro-robot joints.
The selection must strictly match the dynamic load and acceleration curve. It is recommended to use special grease and regular calibration maintenance. The core advantages are sub-micron accuracy, maximum speed and environmental adaptability. It is the core transmission unit of cutting-edge scientific and technological equipment (specific parameters are subject to the manufacturer’s technical manual).
