Clamping bars 2.2095

single acting with spring return 
with press-in or built-in pistons 
clamping force up to 48 kN, piston stroke 6 or 8 mm

The clamping bar is mounted on the press bed or ram using a spacer bar.
Clamping is carried out on the die clamping edge by applying hydraulic pressure to the 5 pistons which are arranged side by side with a pressure medium and mechanical unclamping by a spring return.
Hydraulic oil is supplied through G 1/4 ports provided on both sides.
Flat design with tool insertion slopes.
Clamping force up to 35 kN uniformly distributed over 5 pistons.
When using several clamping bars in a row, the elements are interconnected by means of hoses or pipes.

Clamping bars 2.2096

single acting with spring return 
with built-in pistons 
clamping force up to 116 kN, piston stroke 8 mm

The clamping bar is mounted on the press bed or ram using a spacer bar.
Clamping is carried out on the die clamping edge by applying hydraulic pressure to the 2. 3 or 6 pistons which are arranged side by side with a pressure medium and mechanical unclamping by a spring return.
Hydraulic oil is supplied through G 1/4 ports provided on both sides.
Flat design with tool insertion slopes. 
When using several clamping bars in a row, the elements are interconnected by means of hoses or pipes.

Clamping bar with built-in pistons 2.2096

Clamping bars 2.2097

double acting , with built-in pistons 
clamping force up to 116 kN, piston stroke 8 mm

The clamping bar is directly screwed on the press bed or ram using a spacer bar. Clamping is carried out on the die clamping edge by applying hydraulic pressure to the port of the 2, 3 or 6 pistons which are arranged side by side with a pressure medium. 
Unclamping is made by pressurising the port B. Hydraulic oil is supplied through G 1/4 ports provided on both sides. 
Flat design with die inlet chamfer.
