ABSTRACT:
A hydraulic fastener for mounting bearing assemblies on the end of a roll in a rolling mill stand. The fastener includes a hydraulic ring cylinder component having a front face directed toward a roll and an inner cylindrical surface adapted to fit onto a reduced diameter end section of the roll. A chamber extends about the circumference of the cylinder component and is open at the front face. A hydraulic ring piston component is slidably received in this chamber and has an inner face. A retaining ring is threadedly mounted in the cylinder component to hold at least a substantial portion of the piston in the chamber. Passageways are provided in the cylinder component for injecting grease into the chamber and into a space formed between the inner face of the piston and an opposing face of the chamber. A split ring is secured on the end section of the roll to retain the cylinder component in place. Zero-leakage two-directional seals are arranged between the cylinder component and the piston at both radially inner and radially outer sides of the piston to prevent escape of said grease.
