New hydrodynamic pressure bearing developed successfully

The new hydrodynamic pressure bearing is designed for lightweight equipment, which features 30% lighter than normal bearings. They are made from a large number of Al-Si alloy metal sheets that have been milled into thin sheets. The books were placed in a box that was coated with a high concentration of oil that was resistant to corrosion and corrosion. The inner layer of metal serves as the inner hole of the assembled bearing.
The inner diameter of these seven bearings is only about 1-6 millimeters, and the maximum speed range is 6,000-20,000 revolutions per minute.
