Hydraulic workshop presses are used for axial pressing operations in which components are mounted, dismounted, corrected or positioned under controlled force. The reproducibility of these operations is determined by interference, alignment, support, engagement of load-bearing surfaces and the way in which the force is built up.
Within the HD programme, applications are classified technically to establish within which press class an operation can be carried out, and which structural stiffness, stroke guidance and force capacity are necessary. The application always forms the starting point for technical positioning, not the press model.
This page provides an overview of representative pressing operations in maintenance environments, rework facilities and industrial assembly. Each application is described separately according to fixed technical criteria.
Application as technical starting point
A hydraulic workshop press is not selected on the basis of pressing force alone.
The application determines which technical boundary conditions are relevant, including:
- required pressing force and form of force build-up
- requirements for axial alignment and geometric stability of the workpiece
- support of housings, shafts, hubs or frames
- required stiffness of frame and stroke guidance
- repeatability of recurring mounting or dismounting operations
- sensitivity of components to point loading, misalignment or deformation
Within the HD programme, an application is assigned to a press class only when all technical boundary conditions fall within the range of that class.
Overview of applications
Mounting and dismounting bearings, bushings and plain bearings
Axial mounting and dismounting of bearings, thin-walled bushings and plain bearings in which force introduction, precise alignment and full support determine damage-free interference.

Press-fitting silentblocks and rubber–metal components
Press-fitting of elastic–metallic components in which rubber compression, centring and stable support of the housing determine functional usability.

Press-fitting gears and pulleys onto shafts
Mounting of gears, hubs and pulleys with interference fit onto shafts, in which force introduction via the hub surface and axial shaft support are essential.

Press-fitting and extracting pins and dowel pins
Axial press-fitting and extraction of cylindrical pins under high local loading, in which seat support and precise force introduction are necessary to prevent bore damage.

Press-fitting shafts into and out of housings
Mounting and dismounting of shafts in housings, bearing seats and flange structures — with emphasis on support of housings, centric alignment and control over interference fit.

Press-fitting sleeves, rings and hubs
Axial interference fit of sleeves, rings and hubs in which edge loading, interference and axial stability determine dimensional accuracy and deformation control.

Straightening and aligning workpieces
Straightening of shafts, profiles and structural parts under controlled axial loading, in which frame stiffness and stroke guidance determine the correction process and reproducibility.

Relation between application and press class (HD programme)
An application determines within which press class an operation can be carried out technically. Within the HD programme, three fixed classes are distinguished:
Light-duty hydraulic workshop presses (20–60 tonnes)
For smaller components with:
- limited interference
- short contact length
- simple axial support
- low edge loading
Medium-duty hydraulic workshop presses (80–160 tonnes)
For typical industrial components with:
- normal to increased interference
- longer fits
- need for reproducible force build-up
- stable support of housing or shaft parts
Heavy-duty hydraulic workshop presses (180–500 tonnes)
For large components or stiff structures with:
- high interference
- large diameters or high mass
- need for maximum frame and guidance stiffness
- risk of force peaks due to tolerance accumulation
The final model choice within the HD programme is determined by component geometry, interference conditions, force profile and required repeat behaviour — not by pressing force alone.
Further navigation within the site
Each application page describes:
- the technical character of the operation
- the relevant boundary conditions
- the press classes in which the operation can be carried out
- the next step toward standard models within the HD programme
For applications that fall outside these boundary conditions, reference is made to the separate engineering and custom-built hydraulic press trajectory in which non-standard geometries, complex interferences and deviating mounting conditions are assessed.
Request technical evaluation
When an application falls within the described technical boundary conditions, a technical evaluation can be requested to position the operation correctly within the appropriate press class of the HD programme.
