Hydraulic nuts

Hydraulic nuts HYDNUT, are used to press components with a tapered bore onto their tapered seat. Presses are mainly used if the drive-up forces required cannot be applied using other accessories, e.g. shaft nuts or pressure screws.

The main applications are as follows:

• mounting and dismounting of rolling bearings with tapered bore.The bearings can be seated directly on a tapered shaft, an adapter sleeve or a withdrawal sleeve. The hydraulic nut can also be used for the dismounting of adapter or withdrawal sleeves.
• mounting and dismounting of components such as couplings, gears and ships’ propellers.
