RotoClamp from HEMA is a pneumatic clamping system that, with its two directions of action, enables a wide range of applications. Specifically designed for rotary position clamping, it is available in internal and external clamping versions and is compatible with all common industry shaft sizes. But what if RotoClamp still doesn't fit into your machine layout?

Individual adaptation to special requirements

HEMA's customized adaptations enable the integration of RotoClamp clamping systems into virtually any production machine with rotating guides or drives. After appropriate testing, customized screw or connection hole patterns, as well as modifications to the housing shape, are possible if the specific requirements of a machine assembly space require them. HEMA also implements alternative positioning of the pneumatic connection and customized series with clamping diameters deviating from the standard products.

The functional principle of the RotoClamp remains unchanged regardless of the possible adaptations. This is based on a spring-loaded mechanism in which a spring diaphragm is pressurized with compressed air; this shortens the spring and releases the clamping elements from the shaft. When the compressed air is removed, the spring plates immediately return to their original position and clamp the shaft with great force. A booster function and additional compressed air supply can further increase the clamping force. RotoClamp is equipped with a fail-safe function: If the pneumatic system fails, the axis is immediately clamped with high force..

Users benefit from process advantages

RotoClamp offers users several process advantages that HEMA, with its customized adaptations, can utilize for virtually all machine concepts. The pneumatic system generates high clamping forces even at low pressures, ensuring high production reliability in precision manufacturing. The fail-safe function provides additional safety and minimizes scrap. HEMA's pneumatic clamping systems are a cost-effective solution, as they eliminate the operating and maintenance costs of a hydraulic system.
