Question

Why is hydrostatic bearings called externally pressurized bearings

Answer 1

Explanation:

➡️ Hydrostatic bearings and hydrodynamic bearings are fluid film bearings that rely on a film of oil or air to create a clearance between the moving and stationary elements.In contrast to plain bearings, hydrostatic and hydrodynamic bearings are more expensive and complex in design.

Answer 2

Answer:

Hydrostatic bearings are externally pressurized fluid bearings, where the fluid is usually oil, water or air, and the pressurization is done by a pump. Hydrodynamic bearings rely on the high speed of the journal (the part of the shaft resting on the fluid) to pressurize the fluid in a wedge between the faces.
