RELIABLE COUPLING BOLT
The innovative Superbolt Expansion Bolt(Superbolt ExFit) was created for heavy maachinery that can be easily installed and removed. The Expansion bolt features a tapered sleeve the is split along its length and expands. This design not only eliminates the radial clearance, but also creates a true radial pre-load in operation. no one-sided lift-off of the tapered sleeve from the bore occurs, as the split tapered sleeve remains in steady contact with the bore. The thrust, therefore, remains with the elastic range.
