してなるシールベアリング。 In a sealed bearing in which balls are arranged between an inner ring and an outer ring, and annular spaces on the left and right sides of the inner and outer rings are sealed using a magnetic fluid held by a magnetic ring, there is a gap between the balls and the magnetic fluid. A resin film is formed on the annular seal plate that is attached to the magnet ring, and the magnet ring has a thin film of magnetic material on both sides serving as the poles. A seal bearing in which a groove is formed on the side surface at the convex portion of the outer surface of the seal plate, and convex portions and concave portions of the resin film are formed so as to protrude at the concave portions.
