[Overclocking three new products] LED cooling special FDB dynamic pressure bearing fan


FDB dynamic pressure bearing

Dynamic hydraulic bearings are referred to as dynamic pressure bearings. They are mainly used in the precision machinery industry. They use mucous membrane oil-oil bearings to replace the balls with oil film. The surface of the bearing is engraved with a fish-bone groove. When the spindle rotates, the fluid pressure rises. The lubricant is concentrated inside the bearing and is not easily leaked.

The lubricating oil drifts along the fine groove on the surface of the object, which has the advantage of guiding the concentrated oil in the direction of the rotation of the shaft to prevent oil leakage, ensuring sufficient lubrication of the shaft and reducing friction.


Life expectancy does not reduce noise and does not increase

Since the dynamic pressure bearing oil film is almost free of wear, the fan noise does not change with the passage of time compared to the ball fan!
