SEALING ASSEMBLY FOR BALL OR ROD MILLS AND THE LIKE ABSTRACT OF THE DISCLOSURE An annular seal and a metal washer form a sealing assembly for a bolt fitted to a machine subject to vibra- tions and other forces likely to cause conventional seals to fail. The resilient or deformable seal has a central opening defined by a peripheral sealing edge. The circum- ference of the seal is bevelled to provide other sealing edges. There are sealing beads on opposite faces of the seal near both the opening and the bevelled edges. The relatively non-deformable washer is adapted to bear against the seal and clamp it to a surface of the machine when a nut is tightened on the bolt. This washer has a central opening and an inner face extending to an inclined sealing edge opposing a peripheral sealing edge of the seal. The arrange- ment is such that the annular seal when compressed effec- tively stops the leakage of water and particulate material through the bolt hole.
