High Precision Low Friction Linear Bearing High Durability
As a core component for precision linear motion, linear bearings have become a rigid demand for high-end equipment due to their outstanding performance. Crafted from high-quality bearing steel or stainless steel, the product undergoes precision machining and heat treatment, boasting a repeat positioning accuracy of ±0.01mm, a rolling friction coefficient as low as 0.001-0.003, and a transmission efficiency exceeding 90%.
With a compact structure, it supports combined radial and axial loads. The high-rigidity design suppresses vibration and deformation, adapting to high-speed operation up to 5m/s, while featuring low noise and energy consumption. Some models are equipped with self-lubricating and sealing structures, enabling dust resistance and high-temperature tolerance, along with a long maintenance cycle. Standardized interfaces ensure excellent interchangeability and easy installation.
Widely applied in automated production lines, CNC machine tools, semiconductor equipment, medical surgical robots, industrial robots, 3D inspection instruments, and intelligent logistics systems, it provides stable and efficient linear transmission solutions for scenarios such as laser processing, wafer handling, and precision assembly, safeguarding the accuracy and service life of equipment.
