Superbolt Expansion Bolts Innovative technology for large machinery couplings

Superbolt Expansion Bolts Problems Heavy machinery requires bolting elements that can be easily installed and removed. This is especially true on large and high-performance flange couplings where the bolting elements produce an interference fit for proper torque transfer. However, these type of applications present a number of challenges: Superbolt Expansion Bolts Tensioner A pulls the tapered stud into the expanding tapered sleeve which is split, thus generating a radial force. Machining Requirements Coupling flanges requiring tight or interference fit type bolting elements are expensive to...

Advantages of Superbolt Expansion Bolts • Substantial cost advantages: elimination of time-consuming and destructive removal procedures, expensive repair of distorted bores and also the purchase of new bolting elements. Safety: simple and quick installation and removal, only hand tools are required. Improved worker safety. No honing or machining required: MJTs compensate for small variations. Only line boring of holes is necessary. Re-usable: The Expansion Bolt split sleeve springs back to original size after each removal. Product Development Two simple innovations in the design of the expansion...
