Description:
UNILOCK 5-axis basic module, system size 50 mm, Form B, with rotation lock.

Material:
Carbon steel.

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

Application / Note:
- Can be adapted directly to machine tables with grid holes or T-slots and to grid-hole subplates.
- System size 50 can be combined with system size 80, enabling smaller workpieces to be clamped.
- Fits the UNILOCK zero-point clamping system with UNILOCK clamping pin D = 18 mm.
- Can also be mounted on commonly available zero-point clamping systems if a suitable clamping pin is used.

Clamping Forces:
- With M8 fastening screw: 15,000 N.
- With M10 fastening screw: 25,000 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: B.
- Form-Type: with rotation lock.
- D: 50 mm.
- H: 50 mm.
- SW: 4 mm.
- Retraction force: 10 kN.
- Maximum tightening torque: 10 Nm.
- Drawing references include Dia.18 +0.005/0 mm, Dia.41 mm, Dia.80 mm, Dia.6 H7, M6, M10, 60 mm, 37 mm, 26 mm, 20 mm, 17.5 mm, 13 mm, 12 mm, 8.5 mm and 5.5 mm.
- Height contact surface tolerance: H +0 / -0.006 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: 10 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 10 Nm actuation torque: 10,000 N.
- Axial load: 25,000 N (2.5 t).
- Retraction travel: 0.3 mm.
- Tilt moment, single module: 150 Nm.
- Rotation moment, single module: 25 Nm.
- Lateral force without relative movement: 1,000 N.
- Correct function/repeat accuracy guaranteed up to 1,000 N lateral force.
- Failsafe and personal safety assured up to critical lateral force of 7,000 N.
