Abstract

A seal for rotating shafts, of the type comprising a sheet metal case arranged to be inserted with force into a seat formed in a fixed support and an annular element of an elastomeric material attached to a radial wall of the case and which can circumscribe to the rotary axis, mainly to prevent dripping of the lubricating fluid passing through the seat, characterized in that the metal case has a large central inlet opening in which there is a filtering diaphragm applied to the case with a hermetic seal and having said it joins in its central area a closing element applied to the shaft, thereby ensuring a filtering action of the fluid that penetrating into the cavity of the box reaches the annular closing element.
