Single acting hydraulic clamps

THE IDEAL SOLUTIONS FOR MACHINES EQUIPPED WITH T SLOTS

A typical quick clamping system consists of 4 or more single acting hydraulic clamps which are mounted to both platens. Pressure must be maintained on the clamps and this is in most application achieved by using the EAS change system Air Hydraulic pump unit.

Single acting Hydraulic clamps

  • Spring returned
  • One oil connection

EAS offers the following double acting hydraulic clamps:

  • ERC
  • MLC
  • MTC 

ERC rocker clamps

Single Acting

Working pressure of 350bar

Working Temperature: 0 °C to 200 °C (Viton O-ring installed)
Installation: slides in T-slot (most common) , Fixed on machine plate is also possible

Mould back plate dimensions are not  standardized.

For retrofit applications these clamps can be ideally operated by the EAS change systems Air Hydraulic pump units.

The machine will stop if the hydraulic pressure drops below the defined safety pressure. In case of power faillure the cylinders will stay under pressure and the clamping function remains in operation.

ERC hydraulic rocker clamp

ERC clamps have a T-slot pin. This pin can be adjusted to the actual T-slot dimensions.

Options:

  • M – air movable
  • P – proximity sensor
  • V- check valve
