Description:
Hydraulic rotary lever clamp for compact clamping fixtures.

Application:
For clamping in confined spaces where the workpiece must be removable vertically after the lever retracts.

Features:
- Compact construction
- Drilled-channel oil supply
- No lateral force during clamping
- Compatible with interchangeable K1857 tension levers

Operation:
- The clamping lever is connected to the piston rod
- Double-acting versions release hydraulically
- Single-acting versions release and open by spring force
- The lever moves linearly towards the workpiece and retracts for vertical removal

Load / Force Data:
- Piston force at 100 bar: 7.8 kN
- Piston force at 400 bar: 32 kN
- Effective piston area: 8.04 cm^2

Technical Data:
- Oil volume: 12.9 cm^3

Accessories:
- K1857 tension levers

Notes:
The effective clamping force depends on the selected tension-lever length. Check regularly for dirt, prevent swarf accumulation in the swivel area and align the clamp to provide a horizontal clamping point.
