SEAL RING WITH ENCODER AND ROLLING BEARING UNIT WITH ENCODER

摘要

PROBLEM TO BE SOLVED: To inexpensively actualize construction for shortening a distance between the detected face of an encoder 30b and a detecting portion of a sensor while preventing the wear of the encoder 30b.

SOLUTION: On an inner diameter side core metal 44 of a non-magnetic metal plate, seal lips 43b, 43c and the encoder 30b of a rubber magnetic are vulcanized and molded at the same time with same type adhesive. A back yoke 46 of a magnetic metal plate is attached to the face of the encoder 30b at the opposite side to the inner diameter side core metal 44. This construction shortens the distance while preventing the deposition of foreign matters leading to wear on the encoder 30b.
