Hydraulic Threaded & Threadless Nuts

Installing or removing press fit Rolling Element Bearings (Ball Bearings) on tapered shafts, withdrawal sleeves or adapters at best is both time consuming and difficult. Bearing life can also be extended by insuring proper installation and removal. Hydraulic Nuts make the job easier by making it possible to use “Hydraulic Forces” to insure proper “Drive Up” of the Bearing onto the shaft. The Bearing is first hydraulically pressed onto the shaft to a specified pressure (PSI). Then a dial indicator along with additional hydraulic pressure is used to measure the “Drive Up” in mils (0.001”) required. SKF Hydraulic Nuts are available in both English and Metric threads. Unthreaded versions are also available where you would make use of an existing nut. SKF Hydraulic Nuts are available in sizes from 1.967” to 37.41” (50 to 1,000 mm).
