ROEMHELD B1.8268 Hinge Clamps 70 bar: with throttle valve, metallic wiper edge and optional position monitoring double acting

• Maximum operating pressure 70 bar
• Maximum clamping force: 2,6 - 12,1 kN - 1.3
• Maximum clamping force: 2.1 - 4.1 mm
• Adm. flow rate: 16 - 150 cm³/s

The hinge clamp is a double acting hydraulic cylinder with integrated clamping lever. When pressurising the element, the piston moves upwards and swivels the clamping lever over the hinges forwards and at the same time downwards onto the workpiece. The piston force is deviated by 180° and, depending on the lever length, the force is available as clamping force.

ROEMHELD B1.829 Hinge Clamps with Flat Clamping Lever: with pneumatic position monitoring, single and double acting

• Maximum operating pressure: 250 bar
• Maximum clamping force: 2,5 - 12 kN
• Piston-Ø: 16 - 36 mm
• Clamping height: 23 +1,5/–1,2 - 41 +2,8/–2,3 mm
• Clamping range: ± 1,5 - 3 mm

When pressurising the hinge clamp, a piston moves upwards against the rear edge of the clamping lever and swivels the clamping lever to the clamping position. The piston force is deviated by 180 ° onto the workpiece. The clamping force depends on the operating pressure and the length of the clamping lever.

ROEMHELD B1.8251 Hinge Clamps: with metallic wiper edge and optional position monitoring, double acting

• Operating pressure 250 bar maximum
• Maximum clamping force: 4 - 21.5 kN
• Usable clamping stroke: 4.0 - 9.0 mm adm
• Fow rate 15.7 - 55 cm³/s

When pressurising the element, the piston moves upwards and swivels the clamping lever over the hinges forwards and at the same time downwards onto the workpiece. The piston force is deviated by 180° and is available as clamping force with virtually no loss of efficiency. 

ROEMHELD B 1.7441 Hollow Piston Cylinder: version with internal thread, single and double acting

• Operating pressure 50 bar maximum
• Maximum pushing force: 10 - 153 kN
• Maximum pulling force 10 - 188 kN
• Clamping stroke ranges from 6 to 40 mm
• Piston diameter ranges from 20 to 80 mm
• M6 - M24 internal thread
• M40 - M120 external thread

The pistons of this cylinder range are provided with a through hole and internal thread. In connection with a standard tie rod and C-washer combination a variety of applications is possible. The thread in the piston can be drilled out, if required.
