The ground micro ball screw pair (25mm diameter, 6mm lead) is a high-precision, medium-load transmission component designed for compact precision equipment.
With a nominal diameter of 25mm and a lead of 6mm, it balances speed and precision requirements and is suitable for automation and industrial scenarios.
Using precision grinding technology and high-strength alloy steel, carburizing, quenching and DLC coating treatment, it achieves ±0.005mm level repeat positioning accuracy (C5 level), backlash ≤0.003mm, and excellent rigidity.
The single/double nut preload anti-backlash structure is combined with an end cap ball circulation system, with a rated dynamic load of 10~15kN, a maximum speed of 2000~3000rpm, and supports a wide temperature environment of -30°C to 120°C, with outstanding impact resistance and wear resistance.
Lightweight design (total weight is about 1.5~2kg) and low friction optimization ensure smooth operation, low noise and long life. It is suitable for efficient positioning transmission of CNC machine tool feed axes, industrial robot joints, precision testing platforms, medical imaging equipment and automated production lines.
The selection needs to match the axial load, speed and installation coaxiality. It is recommended to regularly add grease and calibrate maintenance. The core advantages are high rigidity, micron-level precision and adaptability to harsh working conditions. It is an ideal solution for the transmission system of mid-to-high-end equipment (specific parameters are subject to the manufacturer’s technical manual).
