ABSTRACT:
A hemispherical fluid bearing has a pair of inner rings, each having a spherical outer lubricating surface, which are fixed to a shaft, and an outer ring having a lubricating surface corresponding to the lubricating surfaces of the inner rings for supporting the rotation of the inner rings. One of the inner rings and the outer ring has a first film coating of titanium or ceramic formed on the lubricating surface thereof. Therefore, abrasion due to solid friction when a motor starts or stops is efficiently decreased.
