A method of lubricating a bearing for an actuator pivot of a storage device, the method including receiving an assembled bearing for an actuator pivot of a storage device, applying a volume of soap-free oil onto a bearing component of the assembled bearing, and dispensing a predetermined volume of soap-containing grease into a bearing cage.

Oil lubricating process for actuator pivot bearings

A disk drive is disclosed comprising a disk comprising a plurality of tracks, a head attached to a distal end of an actuator arm, and a voice coil motor (VCM) operable to rotate the actuator arm about a pivot bearing including a race and a plurality of ball bearings. The VCM is controlled to execute a first jerk seek in a first radial direction so that the ball bearings slip within the race by a first rotation angle. The VCM is controlled to execute a second jerk seek in the first radial direction so that the ball bearings slip within the race by a second rotation angle, wherein the second rotation angle adds to the first rotation angle in order to rotate the ball bearings relative to the race at a reference angle of the pivot bearing.
