Hydraulic Clamping Cylinders, single and double acting, with and without spring acting.
ROEMHELD B1.8231 Flat Clamp with optional position monitoring, double acting
The flat clamp is a double-acting hydraulic clamping element where the piston acts via a con-rod onto a clamping lever. In unclamped position, the clamping lever is completely retracted and the workpieces can easily be inserted from above.
ROEMHELD B1.8233 Block Clamps: Versions with / without self-locking double acting
Block clamps are double acting hydraulic cylinders. The clamping bolt is supported by a ball bearing and can be swivelled. During the linear extending stroke the clamping bolt with the contact bolt is moved above the clamping point and then swivelled onto the clamping point by means of a wedge drive. The version without self-locking has a smooth wedge surface and requires a constantly available oil pressure
ROEMHELD B1.8241 Slide Pivot Clamps: with optional position monitoring double acting
ROEMHELD B1.8242 Slide Pivot Clamp: compact version, with optional position monitoring, double acting
OBSOLETE ITEM - CONTACT HYQUIP
In the case of the slide pivot clamp the piston force is deviated by 180° by the clamping lever and is available as clamping force with virtually no loss of efficiency. Kinematics of the slide pivot clamp allow sliding back of the clamping lever during unclamping for unimpeded insertion of the workpieces.
ROEMHELD B1.730 Clamping and Supporting Element: self-locking, double acting
OBSOLETE ITEM - CONTACT HYQUIP
The clamping and supporting element is a hydraulic clamping cylinder with mechanical locking according to the wedge principle. Forces which are directed against the clamping force, e.g. machining forces will be supported with a negligible elasticity of the wedge-shaped piston. The counter force must not exceed the maximum clamping force.
ROEMHELD 1.7301 Clamping and Supporting Element: cartridge-type version, self-locking, double acting
ROEMHELD B1.372 Low-Block Clamping Cylinder: single acting with spring return
OBSOLETE ITEM - CONTACT HYQUIP
The preferred application of low-block clamping cylinders are clamping situations where work holding from above is not possible or necessary. The low-clamping effect is caused by the downward motion of the clamping point while the high vertical force guarantees that the workpieces are safely held down.
ROEMHELD B1.711 Hydro Cylinder with Locking Piston single acting with spring return
Hydro cylinders with locking piston are singleacting plunger cylinders, similar to the design of the proved threaded-body cylinders as per data sheet B 1.461. When pressurising the element, the piston will be expanded and locked in the cylinder body.
ROEMHELD B1.490 Slideway Locking Cylinders: single acting without spring return max. operating pressure 500 bar
ROEMHELD B1.494 Spring Clamping Cylinder: pulling, with hydraulic return
