How Can We Help You?

Designed for maximum clamping forces and to address the highest demands concerning reliability, operating comfort and product quality. The innovative multi-forcer piston system offers many advantages compared to conventional ring hub designs. These clamping elements are commonly used in: machine building, the steel industry, refineries, in chemical plants, power plants and off-shore installations, etc.

  • Highest clamping forces
  • Large operating path
  • Simple manual operation (clamping force control)
  • Maximum reliability (counter ring safety)
  • No torsional and lateral forces by clamping
  • Compensation of uneven surfaces
  • Spring return of pistons
  • Leak-proof oil refeed
  • Compact, robust, and corrosion-resistant
