Bearing Installation Methods
The hydraulic nut pushes the bearing into position on a tapered shaft.
The hydraulic nut is screwed onto the shaft to push the withdrawal sleeve into position.
The hydraulic nut pushes the bearing onto an adapter sleeve.
The hydraulic nut can be used together with a lock nut to push the withdrawal sleeve into position.
Product Overview
The SL-HMV Series Hydraulic Nut is designed for the installation and removal of bearings and for hydraulic mounting of keyless or interference-fit connections.
Its operating principle uses ultra-high-pressure hydraulic oil to generate axial thrust on the shaft and expansion force on the sleeve, allowing the shaft and sleeve to be assembled with evenly distributed force.
Product Features
Available with axial or radial oil injection.
Hydraulic pressure is evenly distributed across the pressure ring.
Standard working pressure: 70 MPa or 150 MPa.
Suitable for the installation and removal of bearings.
Custom versions are available for metallurgical, copper, aluminum, and metal processing industries, including hydraulic locking nuts for slitting machines.
Suitable for the installation and removal of propellers, rudder bearings, and similar components.
Suitable for mounting and dismounting high-pressure interference-fit components such as railway wheels, couplings, flywheels, and gears.
The SL-HMV..E Series Hydraulic Nut is suitable for installing and removing tapered-bore bearings with a bore diameter of 50 mm or larger.
Compared with conventional mechanical methods, hydraulic mounting and removal provides a simpler, faster, and more efficient solution.
Available with metric or imperial threads.
Threadless hydraulic nuts are also available for special applications.
When used together with a hydraulic pump equipped with an electronic pressure gauge and a depth micrometer, the hydraulic nut enables accurate monitoring and control of the bearing drive-up distance.
Hydraulic pressure applied to the piston provides sufficient force for accurate, controlled, and safe bearing installation and removal on tapered shafts or sleeves.
Each hydraulic nut is supplied with a quick-connect hydraulic coupling for connection to a hydraulic pump.
Size Range
Metric hydraulic nuts available from SL-HMV 10E (d = 50 mm) to HMV 200E (d = 1,000 mm).
Suitable for shaft diameters from 50 mm to 1,000 mm.
Helps reduce bearing installation time.
Provides accurate and controlled bearing positioning.
Custom thread specifications are available according to customer requirements.
