A canned motor pump includes a main housing with a rotatable shaft carrying an impeller, a high inertia flywheel mounted on the shaft, and a bearing housing stationarily mounted to the main housing. The bearing housing contains a convex radial bearing assembly pivotally mounted on an outer circumferential surface thereof for engagement with a bearing surface on an inner diameter of the flywheel. One embodiment of the convex radial bearing assembly employs a pad made of a self-lubricating, hard material and engageable with a hard metal surface on the inner diameter of the flywheel, and a second embodiment of the convex radial bearing assembly employs a pad with a hard metal surface on the outer diameter of the bearing housing and engageable with a sleeve made of a self-lubricating, hard material and located on the inner diameter of the flywheel.
