Special Issue "Friction and Lubrication of Bearings"

Beside the piston assembly the journal bearings are among the largest contributors to friction in the ICE. Through a combination of measurements and validated simulation methods the journal bearing friction losses of a state-of-the-art heavy-duty Diesel engine are investigated for a large range of real world operating conditions.

Detailed Information on Types of Bearing Lubrication

Lubrication provides a thin film between the contact areas in a bearing to reduce friction, dissipate heat and inhibit corrosion on balls and raceways. The lubricant will affect maximum running speed and temperature, torque level, noise level and, ultimately, bearing life. There are a range of options depending on the application.

Bearing Lubrication. Download PDF of this information. The Role of Bearing Lubricant. Bearing Lubrication plays a vital role in the performance and life of rolling element bearings. The most important task of the lubricant is to separate parts moving relative to one another (balls or rollers and raceways) in order to minimize friction and prevent wear.

Journal Bearings and Their Lubrication

Oil Lubrication. Oils are used in journal bearings when cooling is required or contaminants or debris need to be flushed away from the bearing. High-speed journal bearings are always lubricated with oil rather than a grease. Oil is supplied to the bearing by either .

Hydrodynamic journal bearing [SubsTech]

Journal rotation causes pumping of the lubricant (oil) flowing around the bearing in the rotation direction. If there is no force applied to the journal its position will remain concentric to the bearing position. However a loaded journal displaces from the concentric position and forms a converging gap between the bearing and journal surfaces.

The boundary lubrication is neither planned by the designer and nor desirable. In sliding contact bearing, heavy load on the bearing, insufficient oil supply, low speed of the journal, chemical reactions and misalignment between the journal and the bearing create conditions for boundary lubrication.

Lubricating a bearing once per week or once per month may seem like a sensible thing to do. After all, performing scheduled maintenance at regular periods is an age-old concept. Bearings need grease for one reason only, to reduce friction. As long as the lubricant is performing that service well, there should be no need to change it, or add more.
