PROBLEM TO BE SOLVED: To smoothly perform sampling works of piled sealing units 1 while sliding to a horizontal direction, regarding the sealing unit of a rolling bearing integrating a magnetized member used for rotary detection. SOLUTION: The sealing unit 1 comprises a core metal 2, slinger 3, a circular seal member 4, and a pulser ring 5. The core metal 2 and slinger 3 are combined with each other so that a cylindrical core metal portion 21 and a cylindrical slinger portion 31 are oppositely arranged and a circular core metal portion 22 and a circular slinger portion 32 are oppositely arranged. An outer side 5a of the pulser ring 5 is stuck out by a dimension A more outward than an axial pointed head 21a of the cylindrical core metal portion 21 of the core metal 2 to an axial direction, and an outer side 22a of the circular core metal portion 22 of the core metal 2 is stuck out by a dimension B more outward than an axial pointed head 31a of the cylindrical slinger portion 31 of the slinger 3 to an axial direction. The relationship between the projected dimension A and the projected dimension B is set as A≤B. COPYRIGHT: (C)2004,JPO
