This is provided by a high pressure oil pump which delivers oil between the bearing and journal. The oil, injected under pressure, lifts the mill and helps to reduce the friction between the shoe and ring, providing alignment. The minimum oil viscosity for most mills is 44 cSt at 100°C and typically requires an oil with an ISO 460 Cst viscosity.
