¹) Accuracy is limited if operating below the working range.

To ensure troublefree operation, the angle head always has to be operated with an output drive axial compensator e.g. spindle bearing.

1) Angle head

2) Measurement transducer

You can configure your tightening spindle with a redundant measurement transducer from the same type. Connect both measurement transducers with the adapter.

3) Redundant adapters

When configuring with a redundant measurement transducer, the adapter connects both measurement transducers.

4) Adapters

When configuring without a measurement transducer, the adapter connects the output drive and the planetary gearbox.

5) Planetary gearboxes

6) Transverse gearboxes

The transverse gearbox shortens the length of your tightening spindle by the installation length of the EC motor plus the installation length of the transverse gearbox. The use of a transverse gearbox decreases the tightening spindle working area.
