Workpiece Clamping Elements

ROEMHELD B1.944 Threaded-Body Work Supports: with metallic wiper edge, optional contact control double acting

• Maximum operating pressure 500 bar
• External thread: M30 - M60
• Maximum load force: 6,5 - 42 kN
• Plunger diameter: 16 - 32 mm
• Plunger stroke: 8 - 16 mm
• Elastic deformation: 2,5 - 3,5 μm/kN

In the body of the threaded-body work support a thin-walled locking bush is integrated, which locks cylindrically around the freely-movable support plunger when pressurising the element with hydraulic oil. The support plunger is extended and retracted by means of a small double-acting cylinder.

ROEMHELD B1.890 Swing Clamps with Overload Protection Device: block type, double acting

• Maximum operating pressure 500 bar
• Maximum Operating Pressure: 500 bar
• Piston rod diameter: 20 up to 50 mm
• Maximum clamping forces from 6.5 to 38.5 kN
• Clamping strokes 7 up to 11 mm, total strokes 14 up to 20 mm

These swing clamps are used when it is required to keep the fixture workpiece area free of straps and clamping components for unrestricted workpiece loading and unloading.

ROEMHELD B 1.9472 Threaded-Body Work Supports with metallic wiper edge and long shaft, single and double acting

OBSOLETE ITEM - CONTACT HYQUIP

• Maximum operating pressure 70 bar
• Shaft length 20 – 100 mm
• External thread: M26
• Max. load force: 3 kN
• Plunger diameter: 10 mm
• Plunger stroke: 6.5 mm

The support plunger is hydraulically extended and retracted by means of a small single or double-acting cylinder. Contact to the workpiece is made by spring force. The pressure spring can be easily exchanged. The support plunger is additionally guided in the area of the shaft diameter and can therefore absorb side loads up to 300 N.

ROMEHELD B1.891 Swing Clamps with Overload Protection Device: threaded-body type, single and double acting

• Maximum operating pressure 500 bar
• Maximum clamping force: 4.0 kN
• Rod diameter: 20 mm
• Piston diameter: 23 mm
• Clamping stroke: 7 mm
• Maximum flow rate: 1.5 cm³/s

This design allows the use of swing clamps even in restricted places. The threaded-body swing clamp can be sunk directly into the fixture up to the hexagon. Oil feed through two holes, allowing for 3 fitting and hose connections (see below for options).

ROEMHELD B1.892 Swing Clamps with Overload Protection Device threaded-body type, single and double acting

• Maximum operating pressure 500 bar
• Maximum clamping force: 2.8 - 41 kN
• Rod diameter: 20 - 50 mm
• Piston diameter: 25 - 63 mm
• Clamping stroke: 11 - 15 mm
• Maximum flow rate: 3 - 28 cm³/s

ROEMHELD B1.8921 Swing Clamps with Reinforced Swing Mechanism: threaded-body type, position monitoring optional, double acting

• Maximum operating pressure 500 bar
• Maximum clamping force: 6.8 - 41 kN
• Rod diameter: 32 - 50 mm
• Piston diameter: 40 - 63 mm
• Clamping stroke: 20 - 22 mm
• Maximum flow rate: 20 - 55 cm³/s

Hydraulic swing clamps are used for clamping of workpieces when it is essential to keep the clamping area free of straps and clamping components for unrestricted workpiece loading and unloading.

ROEMHELD B1.8310 Electric Swing Clamps

• Axial pulling force: 3 - 9 kN
•  Top flange, with position and clamping force monitoring
•  DC voltage 24 V
• Minimum energy demand

The electric swing clamp is driven by a brushless DC motor. The motor speed is transformed by means of a gear and a threaded spindle into the swing and stroke movement of the piston rod. For swinging the clamping arm by 180°, an axial stroke of only 3 mm is required.

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.
