Connecting rotating flanges is now even faster with the new patent-pending hydraulically expandable SKF Quickgrip Bolt. The new bolt, as well as the existing SKF Supergrip Bolt, can be used to connect two flanged shafts quickly, safely and reliably. This applies to all types of propulsion systems, as well as rudders and other critical applications. With the new SKF Quickgrip Bolt, maintenance engineers can disassemble and reassemble flanged power transmission couplings in a single-step operation. Once mounted, the bolt is ready to transmit both heavy radial and heavy axial loads, eliminating any potential slippage in the flange coupling.
