Controlled Bolt Loading
Hydraulic Nuts
Hydraulic tensioning, locking, and bearing assembly nuts for controlled loading and heavy industrial applications.
Product Families
Hydraulic nut systems
Hydraulic Tensioning Nuts
Hydraulic nuts for controlled bolt loading and simultaneous tensioning applications.
Typical Applications
- ✓Flange bolting
- ✓Large structural joints
- ✓Critical bolted connections
- ✓Maintenance and shutdown work
Upper Locking Hydraulic Nuts
Hydraulic locking nuts designed for controlled-load applications where preload must be maintained mechanically after pressurization.
Typical Applications
- ✓Heavy equipment
- ✓High-load assemblies
- ✓Critical bolted joints
- ✓Industrial machinery
Bearing Assembly Hydraulic Nuts
Ultra-high-pressure hydraulic nuts for controlled bearing installation and removal.
Typical Applications
- ✓Bearing installation
- ✓Bearing removal
- ✓Shaft assembly
- ✓Rotating equipment maintenance
Hydraulic Preload
Controlled axial loading
Hydraulic nuts apply axial load directly through hydraulic pressure rather than relying only on rotational torque. This makes them useful for large fasteners, bearing installation, controlled preload, and applications where repeatable loading is important.
