ROEMHELD B1.900 Work Supports: Off-position extended – contact by spring force, single acting

• Maximum operating pressure 500 bar
• External thread: M68 - M78
• Maximum load force: 32 - 48 kN
• Plunger diameter: 32 - 40 mm
• Plunger stroke: 16 - 18 mm
• Elastic deformation: 0.9 µm/kN

This spring-loaded plunger positions itself against the workpiece with an adjustable light spring force. Hydraulic locking is made together with hydraulic clamping of the workpiece, or independently. The support plunger is provided with female thread to enable the use of threaded pieces for height adjustment. Oil supply can alternatively be effected from the side or from below. The internal part of the work support is protected against dust and swarf by a sintered metal air filter. Recommended minimum pressure 100 bar.

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 WS 5.3570 - Workholding Systems PC 80 mechanically operated, clamping against the fixed jaw or concentric clamping jaw

Max. Clamping Force:

• PC 80 F: 20 kN at 60 Nm
• PC 80 Z: 20 kN at 60 Nm

 ROEMHELD J7.490 Pneumatic rotary valve couplings made to transfer liquid or gaseous media from a stationary to a rotating component

• Nominal diameter: 3
• Max. operating pressure: 10 bar
• Nominal diameter: 3
• Number of stations: 5 - 8
• Max. operating pressure: 10 bar
• Ports: G 1/4

ROEMHELD J7.201 Pneumatic swing clamp for adjustable, magnetic sensors that only require low clamping forces

• Maximum clamping force: 140 - 1400 N
• Rod diameter: 8 - 25 mm
• Piston diameter: 20 - 63 mm
• Clamping stroke: 7 - 18 mm
• External thread: M30 - M80

When pressurising the element, the clamping arm swings and lowers by 90° to the clamping position and then lowers to the clamping point. The position monitoring gives the required information regarding the position of the piston, but not regarding the position of the clamping arm. Monitoring is made by electronic sensors which detect the magnetic field of the magnetic piston. The switching points can be continuously adjusted by displacement of the magnetic sensors.

ROEMHELD J7.202 Block version pneumatic swing clamp used in applications that require only low clamping forces

• Maximum clamping force: 140 - 1400 N
• Rod diameter: 8 - 25 mm
• Piston diameter: 20 - 63 mm
• Clamping stroke: 7 - 18 mm

When pressurising the element, the clamping arm swings and lowers by 90° to the clamping position and then lowers to the clamping point. The position monitoring gives the required information regarding the position of the piston, but not regarding the position of the clamping arm.

ROEMHELD J7.203 Top flange type pneumatic swing clamp used in applications which only require low clamping forces

• Maximum clamping force: 140 - 1400 N
• Rod diameter: 8 - 25 mm
• Piston diameter: 20 - 63 mm
• Clamping stroke: 7 - 18 mm
• External thread: M40 - M85

When pressurising the element, the clamping arm swings and lowers by 90° to the clamping position and then lowers to the clamping point. The position monitoring gives the required information regarding the position of the piston, but not regarding the position of the clamping arm.

ROEMHELD D8.770 Pneumatic-hydraulic intensifier cna be used as a pressure generator where live cables are not possible or suitable.

• Area ratio: 83 - 25:1
• Displacement: 57 - 188 cm³
• Maximum air pressure 6.3 - 8 bar
• Maximum oil pressure: 195 - 505 bar
• Oil pressure: 140 - 462 bar (at 6 bar air pressure)

ROEMHELD Pneumatic-Hydraulic Intensifier can be used as a pressure generator where live cables are not possible or suitable. Only single-acting cylinders can be connected. The cylinder volume should utilise the working only up to 60-70% so as to have some reserve left.

ROEMHELD B1.733 Position Flexible Clamping Claw double acting, separate locking port, with optional position monitoring, max. operating pressure 250 bar

OBSOLETE ITEM - CONTACT HYQUIP

• Operating pressure 250 bar maximum
• Maximum clamping force is 7.5 kN
• Maximum retention force is 10 kN
• Pendulum range: ±4 mm

The position flexible clamping claw consists of an U-shaped mounting body and the displacably embedded clamping unit with oil supply by two short high-pressure hoses with swarf protection.
