The clamping-support element is a clamping and support element for clamping and supporting workpieces. It has a wedge-shaped self-locking clamping function, double action and a maximum working pressure of 300 bar. The element has the following advantages: one element combines clamping and support functions, wedge-shaped self-locking clamping, hydraulic re-clamping, sudden oil pressure drop, reliable clamping, vibration damping, space-saving embedded cylinder body, arbitrary position installation, interchangeable support screws, and hoses. The element can be used for the following aspects: the workpiece must be firmly clamped even when the hydraulic system pressure drops; the ribs or webs of the workpiece must be clamped and locked in the middle position; the cutting force is relatively high and directly related to the clamping force; the vibration of the workpiece needs to be buffered.
The Roemheld B1.7301 clamping‑support element is a hydraulic component designed for high‑force clamping applications. It features a double‑acting design with a maximum working pressure of 300 bar and can be supplied with oil through either external (明管) or internal (暗管) connections.
The manual covers safety precautions, installation steps, technical characteristics, attachment options, and position‑control features. Detailed specifications such as maximum force, stroke, oil flow rates, and sealing material (FKM) are also provided. This manual is written in Chinese.
| Maximum working pressure | 300 bar |
|---|---|
| Maximum force (retracted piston) | 5.0 kN |
| Minimum release pressure | 140 bar |
The element is rated for a maximum working pressure of 300 bar.
The element can be supplied with oil via external (明管) or internal (暗管) connections using the provided attachments.
The workpiece must be securely fixed, the supporting plate must be positioned correctly, and the oil supply must be properly sealed.
FKM is used as the sealing material for the oil connections.
