Super-precision Bearings

Super-precision bearings are engineered for applications where accuracy, stability, and reliability are non-negotiable. Manufactured with ultra-tight tolerances and refined raceway geometry, they deliver exceptional rotational accuracy, high rigidity, low vibration, and low heat generation—especially at high speeds. With selectable precision grades, controlled internal clearance or preload, optimized cage designs, and tailored lubrication solutions, super-precision bearings help improve surface finish, positioning repeatability, and overall machine performance. They are widely used in machine tool spindles, robotics, precision gearboxes, high-speed motors, pumps, and other advanced motion systems where long service life and consistent performance are required.
