Abstract:
Provided is a magnetic fluid sealed bearing having a stable sealing performance in a gap. The magnetic fluid sealed bearing includes: an inner ring and an outer ring; a plurality of rolling elements disposed between the inner and outer rings; a ring-shaped polar plate mounted on an inner circumferential surface of the outer ring such that a gap is formed between the ring-shaped polar plate and an outer circumferential surface of the inner ring; a ring-shaped magnet attached to the ring-shaped polar plate and magnetized such that magnetic poles thereof point to axial directions, to form magnetic circuits on both an outer ring side and an inner ring side; an inner ring magnetic fluid retained in the magnetic circuit on the inner ring side; and a magnetic field intensity increasing portion for increasing magnetic field intensity of the magnetic circuit on the inner ring side.

Claim (Index 2):
The magnetic fluid sealed bearing of  claim 1 , wherein the magnetic field intensity increasing portion includes the ring-shaped polar plate that is thicker in the inner ring side and is thinner in the outer ring side.
