A support assembly for movable shafts including a bearing for receiving the movable shaft, a bearing housing having an annular housing, in an internal seat that is mounted to the bearing, and a lid to close fluid tight an opening of the seat for the bearing, the cover is made in one piece in a polymeric material and has a portion that is coupled on a radially outer lateral surface for housing the annular element and that is provided with an annular sealing lip which extends frontally projecting from a front edge of the coupling portion, which is made of the same polymeric material of the cover and which is elastically deformable in the radial direction from the inside towards the outside. The annular sealing lip being coupled with interference with a portion of the radially outer conical lateral surface housing the annular element.

Cover for a bearing housing and a support assembly for rotating shaft associated

The bearing seal assembly () includes a metal shield () and a resilient multi-lip sealing gasket () secured to the metal shield. The metal shield is supported in use by an outer ring () of a rolling contact bearing and includes a diagonally extending central portion (). The sealing gasket () provides a number of contacting lips (-) facing an inner ring of the rolling contact bearing. A first, main contacting lip () exerts a first radial load on the inner ring. A second contacting lip () extends from the first lip () and exerts a second radial load on the inner ring lower than the first radial load. A third contacting lip () is on the opposite side of the second lip () with respect to the first lip () and exerts a third radial load on the inner ring lower than the first radial load but greater than the second radial load.
