Hydraulic rotary lever clamp, Style A double, DK=20, Perforated steel channels

Rotary lever clamps are suitable for clamping fixtures with limited space. Due to the compactness of the rotary lever clamps, they can be used in many ways in clamping fixtures with limited space and therefore often allow flexible solutions.
Material:
Housing and piston in steel.
Version:
Burnished housing.
Hardened piston.
Note:
In the rotary lever clamp, the clamping lever is connected to the piston rod. The clamping lever is released and opened by spring tension on single-acting rotary lever clamps, and by pressure means on double-acting ones. The oil supply to the rotary lever clamps is provided through drilled channels.
When clamping with the rotary lever clamp, the clamping lever moves towards the workpiece in a straight stroke and clamps it. To release the workpiece, the clamping lever retracts, so that the workpiece can be removed upwards without collision. The single stroke of a rotary lever clamp depends on the choice of clamping lever.

Tensioning elements must be checked regularly for dirt and cleaned if necessary.
Ensure that, due to the installation position, no chip accumulation forms in the rotation area of the clamping lever of the rotary lever clamp.

The flange surface of the rotary lever clamp must be adapted to the height of the workpiece during installation, and a horizontal positioning of the clamping point must also be available.

By positioning the rotary lever clamp correctly, the tolerances of the parts can be optimally compensated for despite the short clamping lever.

High forces can be generated with the rotary lever clamps. Ensure that the workpieces and clamping devices are designed for these loads.

Rotary lever clamps can be fitted with individual clamping levers. The clamping force of a rotary lever clamp depends on the length of the clamping lever.

The clamping lever for the rotary lever clamp is not included in the delivery.
