ROEMHELD has introduced a hydraulic compact clamp with patented kinematics designed for extremely tight pockets, grooves and recesses. The mechanism first moves horizontally to position the clamping lever, then applies vertical clamping force. Delivering up to 6.5 kN of force, the solution enables space-saving workholding while improving flexibility and efficiency in automated machining and fixture applications.

A newly developed hydraulic compact clamp with horizontal stroke enables direct clamping in the smallest closed pockets, grooves and recesses for the first time. ROEMHELD has optimised the element so that it clamps even workpieces and fixtures in confined spaces with maximum clamping force and high repeat accuracy.

The innovation lies in the kinematics, which are unique worldwide and patented by : The clamping lever first moves horizontally to the point on the workpiece that is to be clamped. It then clamps vertically downwards. This movement sequence allows space-saving workpiece mounting with exact positioning.

Previously, machinists often had to add additional clamping points to components for such clamping tasks and then remove them again in subsequent operations. The new compact clamp avoids the additional costs and extended process times associated with this.

It is particularly suitable for castings, dies, moulds and fixtures that need to be clamped in very narrow grooves, recesses or pockets. Typical applications include multi-sided machining of cast aluminium or grey cast iron workpieces.

Precise and powerful clamping in confined spaces

This new product is available in a space-saving plug-in design. It is offered with either a standard clamping lever or a blank that can be individually adapted to specific workpiece geometries. A quick-fixing mechanism allows for easy changing and increases flexibility for different clamping tasks.

With a clamping force of 6.5 kN at a maximum operating pressure of 220 bar and a horizontal stroke of 8 mm, the hydraulically double-acting clamping element offers high performance despite its minimal dimensions.

The vertical clamping stroke is 4 mm – clamping is possible at any position along the entire stroke. This flexibility enables secure fixing even for workpieces with dimensional tolerances.

Process reliability through integrated controls

For maximum process reliability in automated production environments, the innovation is available in three versions. In addition to a version without position control, variants with pneumatic clamping or unclamping control are also available.

Available immediately

The new compact clamp with horizontal stroke is available now. "With this clamping element, we are solving a problem that many manufacturing companies are familiar with," emphasises Volker Schlautmann, Head of Value Stream at ROEMHELD. "The patented kinematics enable clamping operations that were previously not technically possible or only possible with considerable additional effort. At the same time, the installation position can be flexibly selected, and the plug-in version can be mounted without piping."
