An improved pivot mechanism for a disc drive actuator assembly, the actuator assembly having an E-block which supports an array of read/write heads in reading and writing data relationship to a plurality of data discs, the actuator assembly having a bearing cartridge that rotatably supports the E-block and is receivingly disposed within a bore of the E-block and fixed therein by a tolerance ring interposed in the bore between the bearing cartridge and the E-block. The bearing cartridge has a hollow sleeve that supports the tolerance ring on an outer diameter thereof, and furthermore supports a damping member on the inner diameter thereof. The damping member is attached to the sleeve by a selected damping material.
