摘要：
This rotative assembly comprises a first element rotating with respect to a second element around a rotation axis, at least one bearing arranged between the first and second element, and at least one sealing element arranged between the first element and the second element. The sealing element is housed in a peripheral groove provided on the first element, and comprises at least one sealing lip resting on a surface of the second element. The first element comprises an extraction groove realized on a radial surface of the first element, and which forms an empty space below an internal surface of the sealing element and creates an axial access to said empty space from an axial end surface of the first element.
