ERC hydraulic rocker clamp

Shorten the setup time and optimize your tool clamping process

The ERC rocker clamp is a single acting hydraulic cylinder, designed to fit press platens with T-slots. This enables easy clamping the mold or die.

Improved design

Our R&D department has added special rollers to the design of the ERC hydraulic rocker clamp. Now horizontal as well as vertical machines are supported.

ERC – the perfect fit

The rocker clamp is fitted with a T-slot pin which screws in and out of the clamp base. This allows easy and quick adjustment of the ERC to the DIN 650 T-slot.

ERC T-slot pin
