Technical Description of Shaft with Journal Bearings

Journal bearings execute a sliding motion between a bearing journal and a bearing shell. This sliding motion is usually lubricated by an intermediate medium. The damping effect of the lubricant in the bearing gap means journal bearings run particularly smoothly and quietly. Vibration and shock impact from gear wheels or crank drives are also damped by journal bearings. They are widely used in piston engines, punches and presses as they are insensitive to high shock loads. The journal bearings are grease-lubricated. Grease lubrication allows for a simple bearing construction. consists of a ground steel shaft and two horizontally split pedestal bearings. The upper bearing shell includes a lubrication fitting with a female thread to which a Stauffer lubricator can be screw-fitted by way of an intermediate pipe to supply the bearing with lubricant. The face of the upper bearing shell, which is not subjected to load, contains a flat lubricating slot. This distributes the grease over the full width of the bearing. The grease serves not only as a lubricant but also seals the bearing against external dirt and foreign bodies.
