Description:
UNILOCK clamping module EFM 138 for recessed installation in machine tables, fixtures, plates, cubes and workholding towers.

Material:
Steel.

Version:
Contact faces hardened and ground.

Dimensions / Technical Data:
- D: 138 mm
- D1: 110 mm
- H: 11 mm
- H1: 49 mm
- Operating pressure: 6 bar
- Retraction force with turbo: 20 kN
- Maximum protrusion above installation surface: 11 mm

Application / Note:
- Can be installed in any position, with or without overhang.
- Especially suitable for workholding towers by machining a deep recess for the module.
- Low 11 mm protrusion minimises interference contours and supports horizontal workpiece machining.
- Pneumatic control can be independent or combined for an individual zero-point clamping system.
- Modular layout permits number and spacing of modules to be adapted to the clamping task.
- Integrated spring package maintains clamping without constant air pressure; release is pneumatic.
- Full traction force is maintained during pressure drop or fluctuations.
- Turbo function is standard and recommended for maximum traction force / heavy-feed machining.
