Description:
UNILOCK 5-axis basic module, system size 138 mm, Form A, without rotation lock.

Material:
Carbon steel.

Version:
- Main body oxidised.
- Contact faces hardened and ground.

Application / Note:
- Suitable for clamping large and heavy workpieces.
- Workpiece can be set directly in the basic module using the clamping bolt or reducer adapter.
- Basic modules are fastened via corresponding baseplates or directly to the machine table.
- Flexible positioning is possible.
- A double clamping module can be created by placing two modules together underside to underside.

Clamping Forces:
- With M16 fastening screw: 75,000 N.
- With M20 fastening screw: 160,000 N.
- With M24 fastening screw: 230,000 N.
- Values apply with DIN EN ISO 4762 property class 12.9 cap screws.
- Clamping pins may only be clamped with a mounted interchangeable unit in the clamping module.

Dimensions / Variant Data:
- Form: A.
- Form-Type: without rotation lock.
- H: 75 mm.
- SW: 8 mm.
- Retraction force: 30 kN.
- Drawing references include Dia.138 mm, Dia.25 H7, Dia.12.01 +0.01/0 mm (2x), M16, M12 (4x), 100 +/-0.01 mm spacing, 70.71 mm spacing, 22 mm, 20 mm, 17 mm and 5.5 mm.
- Height tolerance: H +/-0.01 mm.

System Technical Reference:
- Functional slides are closed by manual rotary movement of a threaded spindle with RH/LH threads and lock the clamping pin with frictional force.
- Self-locking: clamping pin remains in the tensioned module even if external tensile force exceeds the retraction force.
- Actuation torque: 30 Nm.
- Repeat accuracy with clamping pin Form A: <0.005 mm.
- Short-cone centring provides precise centring with radii to ease insertion.
- Clamping modules are generally not approved for turning applications.
- Temperature range: +5 degC to +60 degC.
- Retraction force at 30 Nm actuation torque: 30,000 N.
- Axial load: 45,000 N (4.5 t).
- Retraction travel: 0.7 mm.
- Tilt moment, single module: 1,000 Nm.
- Rotation moment, single module: 200 Nm.
- Lateral force without relative movement: 3,000 N.
- Correct function/repeat accuracy guaranteed up to 3,000 N lateral force.
- Failsafe and personal safety assured up to critical lateral force of 20,000 N.
