» Lubriion of bearings at low temperatures

Nov 16, 2000· Lub­ric­a­tion of bear­ings at low tem­per­at­ures. About 80 percent of all bearings are grease-lubried, Grease is a two-phase lubricant, containing base oil (about 80-90 percent) and a thickener. There will also be additives such as anti-corrosion agents, anti-wear and anti-weld (so called extreme pressure, or EP) additives.

Numerical Unsteady Analysis of Thin Film Lubried

A thin film lubried journal bearing is to develop positive pressure by virtue of relative motion of two surfaces separated by a fluid film. Thin film bearings are those in which although lubricant is present, the working surfaces partially contact each other at least part of the time. These bearings are also called Boundary Lubried Bearings.

Hydrostatic and Hydrodynamic Bearings Selection Guide

Plain bearings are simple, inexpensive bearings inwhich the shaft comes in contact with the bearing surface during operation, and uses a lubricant to reduce the friction between the sliding surfaces. In contrast to plain bearings, hydrostatic and hydrodynamic bearings are more expensive and complex in design.
