Various aspects of the present disclosure are directed toward a disc drive actuator assembly including an e-block, a plurality of bearings, and one or more heat transfer components. The heat transfer component(s) operates to conductively draw heat from the plurality of bearings through the e-block, and convectively dissipate the heat into an atmosphere in contact therewith. The heat transfer component(s) mitigates temperature rise of the bearings during operation of a disc drive, thereby mitigating bearing lubricant outgassing from within the bearings.
