係合させたことを特徴とするマグネツトロール。[Claims for Utility Model Registration] A permanent magnet member formed in a cylindrical shape and provided with a plurality of magnetic poles extending in the axial direction on its outer peripheral surface, and a sleeve formed in a hollow cylindrical shape from a non-magnetic material,
In a magnet roll that is coaxially and relatively rotatably fitted through a flat plate flange and a shafted flange, a shaft is coaxially protruded from one end of the permanent magnet member, and a bearing is attached to this shaft. A flat plate-shaped flange is interposed through the permanent magnet member, and a ring-shaped concave curved surface is provided coaxially on the other end of the permanent magnet member, and a ring-shaped convex curved surface corresponding to the concave curved surface is formed using a self-lubricating material. A magnet roll characterized in that the formed shafted flange is slidably and rotatably engaged with the permanent magnet member through the uneven curved surfaces.
