identifying and analyzing 12 primary causes of bearing failure. Each characteristic is described in detail and is shown in diagram form, accompanied by a color photograph. Flaws, in most cases, are readily apparent. In some cases, the imperfections may be virtually invisible to the naked eye.
In addition, lubrication protects the bearing against corrosion and wear, helps dissipate heat, helps seal out solid and liquid contamination, and reduces bearing noise. A properly lubricated bearing has the best chance of reaching its maximum service life. As with bearings themselves, there are numerous causes for lubricant failure, including:
Plain bearings are used for high radial loads (perpendicular to the axis of the shaft) and low to high speeds. Typical applications include turbines, large milling systems, engine cranks, compressors, gearboxes, shaft bearing supports, etc. Every sleeve bearing has some common design characteristics as shown in Figure 2.
