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.

• Maximum load force: 20 kN
• Plunger diameter: 32 mm
• Plunger stroke: 12 mm
• Maximum flow rate: 35 cm³/s
• Elastic deformation: 1.3 µm/kN

Work supports are used to provide a self-adjusting rest to avoid deflection and vibration of the workpieces during machining. It is recommended to use double-acting elements if applied in larger hydraulic clamping fixtures with long lines, especially if the return oil is cycled and has to return in a predetermined time.

ROEMHELD B1.910 Work Supports: Extending hydraulically – contact by spring force, single acting with spring return

• Maximum operating pressure 500 bar

• Plunger stroke: 18 mm
• Maximum flow rate: 70 cm³/s
• Elastic deformation: 1 µm/kN

With the B1910 range the support plunger is retracted in off-position. When pressurised the support plunger moves against the inserted workpiece by means of spring force. With increasing oil pressure, the plunger locks hydraulically. After the system has been unclamped, the support plunger returns to off-position. The support plunger is provided with female thread to enable the use of threaded pieces for height adjustment. 

ROEMHELD B1.9471 Threaded-Body Work Supports: with metallic wiper edge, double acting

• Maximum load force: 3 - 10 kN
• Plunger diameter: 10 - 16 mm
• Plunger stroke: 6,5 - 10 mm
• Elastic deformation: 5 - 9 μm/kN

The support plunger is hydraulically extended and retracted by means of a small double-acting cylinder. Contact to the workpiece is made by spring force. The pressure can be easily exchanged. Locking of the support plunger through the slotted clamping sleeve is made by means of a ringshaped conical hydraulic piston where the locking force is transmitted by a low-friction ball shell. Unlocking of the support plunger is made by spring force.

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

• Maximum operating pressure 500 bar

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.
