61040 - Piher Maxipress R 40 High-Performance Piston F-Clamp 16-Inch

High-Performance Industrial Clamping Solution

The Piher Maxipress R 40 (SKU: 61040) represents the pinnacle of heavy-duty clamping technology, specifically engineered for the rigorous demands of the metalworking and industrial sectors. Unlike traditional F-clamps that expose their screw threads to the environment, the Maxipress R features a revolutionary fully enclosed piston system. This design innovation is critical for industrial applications, as it completely shields the internal thread mechanism from dust, metal shavings, and other contaminants that typically degrade clamp performance over time. The piston action allows the clamp to deliver a massive 1000 kg (2200 lbs) of clamping force with minimal user effort, thanks to the efficient double-threaded screw design.

Structurally, the Maxipress R is built to withstand extreme stress. The jaws are constructed from nodular cast iron, a material chosen for its superior ductility and resistance to impact compared to standard grey iron. This ensures that the jaws will not crack under high pressure. Connecting the jaws is an extra-resistant rolled steel bar measuring 35mm x 8mm, boasting a strength rating of 90 kg/mm². This robust rail minimizes flexing and bowing, ensuring that the clamping force is applied squarely and effectively to the workpiece. The fixed jaw also features a grooved surface, allowing for the secure holding of pipes, tubes, and other rounded profiles, adding to the tool's versatility in a mixed-fabrication environment.

Maintenance and longevity are core aspects of the Piher design philosophy. The Maxipress R includes an easily accessible grease hole, allowing users to lubricate the internal mechanism without disassembling the tool. This feature ensures smooth operation and consistent pressure generation throughout the tool's lifespan. Additionally, the moving jaw is equipped with a non-slip brake system that prevents the jaw from sliding down the bar when positioned vertically, a common frustration with lesser clamps. For professionals seeking a clamp that combines raw power with intelligent protection against industrial elements, the Piher Maxipress R is the definitive choice.
