MAGNETIC ENCODER AND ROLLING BEARING

摘要

A magnetic encoder (16a) comprises a plastic multipolar magnet (23a) which is formed in a disk shape and has a through hole at its center and magnetic poles alternately arranged in the circumferential direction and a slinger (24a) which has a cylindrical part (28a), a flange (28b) extending from one end of the cylindrical part (28a) radially outwardly, and a flange part (28c) extending from the radial outer end of the flange (28b) in the radial direction and the cross section of which is formed in a generally inverted Z-shape. The multipolar magnet (23a) is press-fitted into the radial inner side of the flange part (28c) and held by the slinger (24a).
