Bearing Damage: Lining Extrusion and Cracking

Lining extrusion and cracking may be caused by overheating, which can reduce the strength of linings so that the material yields and cracks from the effect of normal and shear forces transmitted through very thin oil films. Wiping does not necessarily occur under such conditions.

Addressing the Damage

Fit new or reconditioned bearing pads.

To prevent future damage, investigate and, if possible, reduce the maximum operating temperatures.
