Abstract

An apparatus includes at least one actuator shaft. First and second head stack assemblies are coaxially located on the actuator shaft(s). The first and second head stack assemblies each include: at least one bearing having an inner race coupled to an outer surface of the actuator shaft(s); an E-block surrounding an outer race of the at least one bearing; an annular gap is between the E-block and the outer race of the at least one bearing; a ring of bonding material filling the annular gap; and an access gap providing a fluid path to the annular gap from at least one of a top and a bottom of the E-block.
