Our pivot assembly bearing unit meets the demands of micron unit head drive control of H.D. D which accelerates the increase in capacity. This unit assembles and supplies two high precision bearings and precision machined parts under pressurized insertion or adhesion under strict preload control. Pivot assembly bearing unit is produced by fully automation facility.

■By combining high precision bearings and precision machined parts, excellent rotation accuracy can be obtained.
■Two bearings are assembled and supplied by press fitting or adhesion under proper preload control.
■Low torque and low torque fluctuations can be obtained by proper selection of bearing grease, filling amount, filling method.
