ROEMHELD I4.130 Fixture Clamp, Position Flexible max. clamping force 8 kN, jaw width 40 mm double acting, max. operating pressure 250 bar compensate machining forces from all directions.

• Maximum clamping force: 8 kN
• Maximum retention force: 10 kN
• Jaw width: 40 mm
• Clamping stroke: 2x 8 mm
• Maximum flow rate: 17 cm³/s
• Maximum operating pressure 250 bar

This fixture clamp with position-flexible clamping function consists of a very slim basic body with 2 integrated hydraulic cylinders. The piston forces are transmitted by two channels to the two clamping slides that can be moved independently from each other. During clamping both clamping slides contact the workpiece nearly without force.

ROEMHELD H4.307 Parallel Slide Centering Element: double acting

• Maximum operating pressure 500 bar
• Clamping force / jaw: 2.8 - 8.8 kN
• Stroke / jaw: 6 - mm
• Piston Ø: 12 - 20 mm
• Centering repeatability: ±0.02 mm

By a clever arrangement of the centre of rotation to the hydraulic piston the retaining force of a clamping jaw is three times higher than the clamping force. If only one clamping jaw acts at the workpiece, the clamping force is twice as large. This happens as long as the workpiece is moved to the centre.

ROEMHELD F9.428 Threaded-body and Built-in type Coupling Elements.

• Nominal diameter: ND 3 - 8 
• Max. flow rate: 8 - 35 l/min
• Coupling stroke: 4.5 - 7.4 mm
• Max. coupling force: 2.4 - 8.4 kN
• Positioning tolerance, axial: +0.5 mm

ROEMHELD D8.013 Power units with two-hand operator console

• Flow rate: 0.9 - 4.5 l/min
• Operating pressure: 160 - 500 bar
• Reservoir volume: approx. 11 l
• Usable oil volume: approx. 6 l
• Connections: G 1/4
• Motor: 0.75 - 1,1 kW – 400 VAC

Two-hand operator console is required for fixtures and installations with dangerous applications, in order to keep hands from the effective area of the dangerous movement. Both mushroom push-buttons have to be operated simultaneously within 0.5 seconds. The basic housing of the two-hand operator console is made of plastics and equipped with two mushroom push-buttons and one emergency palm button.

ROEMHELD C 2.360 Electrically Operated Directional Control Valves with Socket Adapter ND 4

• Port size: G 1/4
• Adm. flow rate: 8 l/min
• Hydraulic oil: HLP 22
• Nominal voltage: 24 VDC
• Code class: IP 54
• Electrically Operated
• with Socket Adapter
• Maximum Operating Pressure: 350/500 bar

ROEMHELD B1.940 Single Acting Threaded Body Work Supports

• Maximum operating pressure 500 bar
• M30 external thread
• Maximum load force: 6.5 - 9.5 kN
• Plunger diameter: 16mm
• Plunger stroke: 8 - 15mm
• Maximum flow rate: 25 cm³/s
• Elastic deformation: 4 µm/kN

Hydraulic work supports are used to provide a self-adjusting rest for the workpiece during the machining operations. They compensate the workpiece surface irregularities, also deflection and vibration under machining loads. Two sizes are available. The threaded-body design of the elements allows direct installation in clamping fixtures, in horizontal or vertical mounting position, and thereby a space-saving arrangement.

ROEMHELD B1.8500 Swing Clamps with Sturdy Swing Mechanism: Top flange type, with optional position monitoring, double acting

• Maximum operating pressure 70 bar
• Maximum clamping force: 2 - 13.3 kN
• Rod diameter: 14 - 36 mm
• Piston diameter: 25 - 65 mm
• Clamping stroke: 8/10 mm
• Maximum flow rate: 13 - 167 cm³/s

The hydraulic swing clamp is a pull-type cylinder where a part of the total stroke is used to swing the piston. Due to the sturdy swing mechanism the angle position of the clamping arm remains the same after a slight collision with the workpiece during loading and unloading or during clamping. The angle position of the clamping arm is fixed with a dowel pin.

ROEMHELD B1.8252 Mini Hinge Clamp: with metallic wiper edge, double acting

• Maximum operating pressure 250 bar
• Maximum clamping force: 2.2 kN
• Usable clamping stroke: 3 mm
• Adm. flow rate 8 .. 15 cm³/s

ROEMHELD B1.8242 Slide Pivot Clamp: compact version, with optional position monitoring, double acting

OBSOLETE ITEM - CONTACT HYQUIP

• Maximum clamping force: 10 kN
• Operating pressure 350 bar maximum
• Clamping stroke: 5.5 mm

In the case of the slide pivot clamp the piston force is deviated by 180° by the clamping lever and is available as clamping force with virtually no loss of efficiency. Kinematics of the slide pivot clamp allow sliding back of the clamping lever during unclamping for unimpeded insertion of the workpieces.

ROEMHELD B1.4841 Bore Clamps: Block-type, without centring function, double acting, for bore diameter 7.8 - 17.7 mm, max. operating pressure 250 bar

OBSOLETE ITEM - CONTACT HYQUIP

• Double acting
• Operating pressure 250 bar maximum
• Bore hole diameter ranges from 7.8 to 17.7 mm
• Maximum low-clamping force 5.1 - 9.8 kN
• Expansion force , radial: 9 - 14 kN

This bore clamp is a double-acting pull-type cylinder. An exchangeable clamping bushing is fixed to the piston. The four segments of the clamping bushing are radially expanded with spring force by a pyramid-shaped clamping bolt. Thus the expansion force is always the same and independent of the hydraulic clamping pressure.
