In a fluid dynamic bearing (FDB), a thin layer of oil or other lubricant is injected between the shaft and sleeve. The structure of the bearing features a rotating shaft, which generates a hydrodynamic force, causing the shaft to rotate. The non-contact construction of this bearing makes it particularly suited for improving rotational accuracy and enhancing quietness and robustness. Demand for FDB from a high-precision HDD spindle motor is expected to soar in the future.
