Micro-pitting and wear assessment of engine oils operating .

Morales and Brizmer further showed that even without the presence of additives, wear and micro-pitting are indeed two competing mechanisms acting on the surfaces operating under boundary/mixed lubrication conditions. They showed that micro-pitting damage depends on the lubrication condition and roughness of contacting surfaces.

Failure mechanisms of ball bearings under lightly loaded .

Fig. 2 is a schematic of the test setup. Axial and radial loads of 0.39 N and 0.70 N were applied to the ball bearings. The equivalent radial load (1.17 N) under this loading condition was only 0.7% of the static radial load rating (179 N) of the bearing, and was below the fatigue load limit (8.14 N) of the bearing .Thus, the ball bearings were lightly loaded throughout the tests.

Speed limitations - skf.c

It is possible to operate a bearing at speeds above its reference speed, its adjusted reference speed, or even the limiting speed. Before doing so, first make a detailed thermal analysis, and take whatever further measures may be required, such as use of special cage executions, or consider using high precision bearings.

Plant and Equipment Health Measurement, Assessment and .

An example is misalignment leads to bearing overload, then to lubrication breakdown, then to metallic stress due to bearing wear, followed by bearing failure, and finally to equipment failure. With HI analysis used in the Plant Wellness Way philosophy you would correct the misalignment so there could be no opportunity to overload the bearing.
