Single pneumatic port activation – independent zero‑point clamping with simple on/off control
High repeatability – ±0.005 mm (0.0002″) for precise and consistent pallet changes
Long rectangular base – 185×135 mm footprint offers increased mounting stability
Taller profile – 90 mm height provides additional clearance for fixture stack‑ups
Heavy pull‑down & clamping force – 55 kN (12,364 lbf) pull‑down / 17 kN (3,822 lbf) clamping
High max. air pressure – operates up to 1.2 MPa (174 psi) for demanding applications
Hardened steel construction – wear‑resistant body for high‑duty production cycles
Large fixture plates – longer base distributes clamping load evenly across bigger pallets
Vertical machining centers (VMCs) – extra height improves accessibility for manual loading
Automated pallet systems – repeatable zero‑point locking for robotic work cells
Tombstone fixtures for HMCs – multiple units mount securely on each tombstone face
Heavy workpiece clamping – 55 kN pull‑down secures large or unbalanced parts
Stable rectangular footprint – resists rotation and torque better than square or round bases
Taller design – 90 mm height allows integration with custom risers or sub‑plates
Precision ground locating surfaces – each unit verified for flatness and lock repeatability
Pneumatic only – no hydraulic power unit needed, simplifies shop floor setup
Custom mounting hole patterns – available upon request for non‑standard machine tables
