An improved hydrodynamic bearing design and method for fabricating a hydrodynamic bearing is disclosed, which incorporates a filling groove so that oil or other lubricating fluid can be efficiently inserted into the bearing gap without risking the loss of fluid during operation; the method provides for fabricating the hydrodynamic bearing and its oil filling groove so that the efficiency of the manufacturing process is not compromised. The same grooving tool which forms the hydrodynamic bearing is scraped across an abutment on the sleeve which supports the counterplate to form a shallow filling groove under the counterplate.
