Work Supports

ROEMHELD B1.921 Work Supports: contact by spring force or air pressure, single acting

• Maximum operating pressure 500 bar
• Cross section of the body: 60x35 - 85x63 mm
• Maximum load force: 7 - 28 kN
• Plunger diameter: 16 - 35 mm
• Plunger stroke: 6 - 10 mm
• Maximum flow rate: -
• Elastic deformation: 1.3 - 3.6 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.

ROEMHELD B1.930 Work Support, Self-Locking: with pneumatic position monitoring, 3 sizes, 2 types of function, double acting

• Max. operating pressure 500/400 bar
• Cross section of the body: 70x48 - 140x105 mm
• Max. load force: 8 - 40 kN
• Plunger diameter: 16 - 40 mm
• Plunger stroke: 8 - 20 mm
• Max. flow rate: 25 cm³/s
• Elastic deformation: 0.7 - 1.0 µm/kN

ROEMHELD B1.9405 Threaded Body Work Supports: M 26 x 1.5, with metallic wiper edge, 3 types of function, single acting

• Max. operating pressure 350 bar
• External thread: M26
• Max. load force: 4 kN
• Plunger diameter: 16 mm
• Plunger stroke: 6.5 mm
• Max. flow rate: 25 cm³/s
• Plastic deformation: 3 µm/kN

ROEMHELD B1.943 Threaded Body Work Supports 3 function types, with metallic wiper edge, optional contact control single 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
• Maximum flow rate: 25 cm³/s
• Elastic deformation: 2.5 - 3.5 µm/kN

In the body of the threaded-body work supports a thin-walled locking bush is integrated, which locks cylindrically around the freely-movable support plunger when pressurising the element
with hydraulic oil.

ROEMHELD B1.9470 Threaded-Body Work Supports: with metallic wiper edge, single acting

• Maximum operating pressure 70 bar
• External thread: M26 - M45
• Maximum load force: 3 - 10 kN
• Plunger diameter: 10 - 16 mm
• Plunger stroke: 6.5 - 10 mm
• Maximum flow rate: 25 cm³/s
• Elastic deformation: 3.5 - 9 μm/kN

The support plunger is hydraulically extended by a small piston and contacts the workpiece with spring force. The pressure can be easily exchanged. Locking of the support plunger through the slotted clamping sleeve is made by means of a ring-shaped conical hydraulic piston where the locking force is transmitted by a low friction ball shell. Unlocking and retracting of the support plunger is made by spring force.

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 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.
