Function
The DEMA (rotary unit around the motor axis) enables the targeted rotation of a nutrunner with angle output drive around its motor axis.

Features
Designed for mounting torques of approx. 100 Nm to 500 Nm (depending on version).
Swivel range from 270° to 360° – optionally with end stops or freely rotatable.
Option for continuous setting of the end stops (depending on variant).
Needle-bearing rotary motion for precise, smooth-running rotation.
Integrated clamping sleeve for nutrunners with diameters from Ø35 to Ø65 mm.
Can be expanded with functions such as swivel angle monitoring as well as indexing or latching.
High variability for adaptation to different tightening positions and applications.

Use
Suitable for industrial assembly applications where a nutrunner with angle output drive must be rotated between multiple tightening positions. Supports ergonomic working, improves accessibility to tightening positions, and enables reproducible positioning in the process.
