Bearing Storage
Self-lubricating or oil saturated, powdered metal, sintered bronze, bearings typically contain 25 % oil, by volume. This quantity of oil is generally sufficient for the life of the bearing. An oil film is created between the bearing and the shaft due to elastic deformation and due to capillary action caused by the temperature in the bearing rising because of the friction generated during operation. As the bushing material expands, the oil weeps out lubricating the contact surface and at higher speeds, a hydrodynamic film is generated.
