Abstract
A sliding bearing which is mounted on a shaft (2) and is composed by a magnetized material, whereby between the sliding bearing (1) and a surrounding bearing housing (5) is provided a magnetic fluid as lubricating and sealing agent. The sliding bearing (1) has sliding shoes (3) adapted at rotation of the shaft (2) to cause a compression of the fluid volume and to urge fluid to pass out under the sliding shoes at the same time as the hydrostatic pressure increases in the spaces (4) between the sliding shoes (3).
