The oil-injection method used for removing the reusable bolts was pioneered by SKF. Originating in Sweden, this technology is based on nearly a half century of experience in the engineering and manufacture of couplings for the marine market, and since the late 1970s, for the utility industry also. Brochure: SKF Supergrip Bolt for rotating flanges.The hydraulic pump is connected to the center of the bolt. Oil is injected to release the bolt from the sleeve. The bolt slides out of the taper and the sleeve immediately regains its original diameter.

The latest generation of Supergrip bolt, for example, is based on the oil injection method developed in the early 1940s. The technology has been advanced over the years to develop different connection systems with new mechanisms to save time and money, while increasing safety across a wide range of applications.
