Expansion bolting
Utilizing Superbolt technology, Nord-Lock is able to offer tremendous radial expansion and joint clamping power in one bolting system. The Expansion bolts replace traditional interference or force fit bolts. Radial expansion is critical for rotating couplings or alignment systems that require the bolts to be able to transfer forces in shear.
The key to this technology is the split expansion sleeve that mates with the customer’s machined holes. The split sleeve requires less tolerance on mating parts than is traditionally required with interference fit or hydraulic systems, saving critical machining time.
