Abstract

The secondary sealing element has a cross-section that is limited by a pair of radially spaced outer and inner circumferential areas (20, 21) and a pair of axially spaced end areas (22, 23) from which an open angle (alpha), stemming from the outer to inner circumferential areas, opposite a radially inclined sloping area (23). The neighbouring circumferential and end areas have, at right angles, a recess on the sloping area. There is a ratio K, between the radial and axial cross section dimensions of the secondary sealing element, that lies in the region of 0.7 and 1.2 according to the equation: K = D - d/ B Where D = Diameter of the outer circumferential area (21) d = Diameter of the inner circumferential area (20) B = Width of the secondary sealing element of the outer circumferential area. The angle (alpha) may be between 2 and 15 degrees.
