A lubrication method in which oil is splashed and brought into the bearing through other running parts.

The oil supply amount of splash lubrication is not easy to adjust, and the lubricating oil level cannot be too high, otherwise it is easy to cause stirring loss and temperature rise, and it is also easy to bring impurities in the oil tank into the bearing and damage the bearing.

In splash lubrication, oil is splashed onto the bearing by a rotating body (impeller or "slinger") mounted on the shaft, and the bearing is not immersed in oil.

Experience: In gearboxes, gears and bearings often share an oil tank with the gear that serves as an oil slinger. Since the viscosity of the gear oil may be different from that required by the bearing and the oil contains wear particles from the gears, a separable lubrication system or method can be used to improve bearing life.
