Hydro-Dynamic-Bearing
The Hydro Dynamic Bearing (HDB) technology and the fan’s oil seal design provide more reliability than conventional motor fan designs.
1. High revolution precision, low vibration noise
2. The fluid seal design provides an extremely long lifespan
3. Surface tension effect: smoother performance, less friction, extremely quiet.
The fluid seal design is based on the use of oil surface tension and hydrodynamic pumping forces. The internal area of the bearing’s design drives the oil towards the right areas and prevents oil leakage (which is one of the main problems of sleeve bearing fans, severely shortening their useful life), while the herringbone structure further reduces friction, allowing HDB fans to reach higher levels of reliability and noise minimization.
