Abstract
An actuator pivot bearing is disposed at least partially within a pivot bearing bore of a disk drive actuator. The actuator pivot bearing includes a fixed inner bearing shaft having a lower portion that is attached to the disk drive base. It may also have a rotatable outer bearing sleeve that is attached to the actuator body. The actuator pivot bearing also includes an adsorptive element (e.g. comprising activated carbon, silica gel, zeolites) disposed between the fixed inner bearing shaft and an inner surface of the pivot bearing bore. In certain embodiments, the adsorptive element may optionally be disposed within an actuator pivot bearing internal cartridge space. A restricted clearance between the rotating and fixed bearing components may partially block a diffusion path from the pivot bearing lubricant to the read head. The adsorptive element may be disposed adjacent that restricted clearance.
