Mounting bearings on tapered seatings can be a difficult and time-consuming job. Using an SKF Hydraulic Nut facilitates easy and quick application of the high drive-up forces required for mounting bearings. Dismounting bearings mounted on either adapter or withdrawal sleeves is also often a difficult and time-consuming job. These problems can be reduced with the use of an SKF Hydraulic Nut. Oil is pumped into the nut and the piston is pushed out with a force, which is sufficient to free the sleeve. All SKF HMV ..E nuts are supplied with a quick connection coupling to fit the SKF hydraulic pumps. 

• Wide size range, covering shaft diameters from 50 to 1 000 mm as standard
• Full range of inch threads available, series HMVC ..E from 1.967 up to 37.410 in.
• Quick connection coupling can be fitted on the face or side of the nut, allowing the nut to be used in areas where space is limited
• A spare set of piston seals and maintenance kit is supplied as standard
• To assist nut threading, a tube of lubricant is supplied with all nuts of size HMV(C) 54E and larger
• To facilitate easy nut threading, all nuts from size HMV(C) 54E are equipped with two tommy bars and four mating holes on their front face
• Nuts from size HMV(C) 94E are equipped with eyebolts, allowing easy handling
• Nuts from size HMV(C) 94E have the starting position of the thread indicated, facilitating easy matching of thread positions on both the nut and mating thread
• Special threads and sizes available on request

Maximum working oil pressure with permitted piston displacement of HMV(C)…E nuts: 

• HMV(C) 60E and smaller: 80 MPa (11 600 psi)
• HMV(C) 62-100E: 40 MPa (5 800 psi)
• HMV(C) 102E and larger: 25 MPa (3 600 psi)
