低摩擦密封组件,能够插入在带凸缘的转动元件与静止元件之间限定出的环形空间中以保护滚动构件;转动元件设置有凸缘和安装座,安装座由圆柱底壁以及由布置在凸缘的相对侧的轴向肩部界定,密封组件具有环形遮蔽件,其设置有:套筒部分,其在使用期间与转动元件在安装座内成一体,并相对于转动元件由侧向安装表面界定;和凸缘部分,其从套筒部分径向突出地延伸;环形遮蔽件的套筒部分的内径的标称尺寸与安装座的圆柱底壁的外径的标称尺寸相同,轴向肩部具有进入边缘,进入边缘具有圆锥形状,以便将环形遮蔽件安装于转动元件,并且轴向肩部相对于安装座的圆柱底壁的外径的径向厚度的尺寸使得防止环形遮蔽件的套筒部分在安装步骤期间发生塑性变形。

    Low-friction sealing assembly for a vehicle wheel-hub unit to be inserted in an annular space defined between a flanged rotating element and a stationary element, to protect at least one ring of rolling members arranged between the stationary element and the rotating element; the flanged rotating element being provided with a flange and a mounting seat delimited by a cylindrical bottom wall and by an axial shoulder arranged on the opposite side to the flange. Nominal dimensions of an internal diameter of a sleeve portion of an annular screen are substantially the same as nominal dimensions of an outer diameter of a cylindrical bottom wall of the mounting seat, and the axial shoulder has an entry edge with a substantially conical form for facilitating mounting of the annular screen on the rotating annular element.
