A structural unit for assembly to a trunnion of a universal joint bearing providing a cup, a sealing ring, which is fixed to the cup, and a shield, which is connected to the cup in a state in which the structural unit is not assembled to the trunnion. The cup includes a bottom and the sealing ring provides at least one sealing lip that points in a direction with an axial component towards the bottom.

Structural unit, universal joint bearing and assembling procedure

Sealing unit adapted to be coupled to a rolling-element bearing to seal off the annular space between an inner ring and an outer ring of the bearing, the sealing unit having a stiffening core, and an elastomeric annular element that is rigidly secured to the stiffening core and provided with a sealing lip and a root portion, which is positioned radially on the opposite side of the sealing lip, and which can be snap-fitted into a groove of the outer ring in order to abut the root portion on a front wall of the groove with the core facing toward the outside of bearing.

Sealing unit for rolling-element bearings

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.
