The core design of ultra-precision angular contact thrust ball bearings lies in their large contact angle (typically 60°) and high-precision matching steel balls, which can simultaneously withstand heavy axial loads and radial loads. With optimized raceway geometry and cage, they achieve extremely low friction and high rigidity, ensuring that they maintain nanometer-level rotational accuracy and excellent axial positioning capability during high-speed operation.
