Live-Shaft Roller Installations
Tension feedback for rollers using live-shaft mounting structures.
Through-Shaft Tension Sensor
LF100A is a live-shaft flange tension sensor with built-in self-aligning ball bearings. It helps compensate for shaft installation errors and provides stable web tension feedback for converting and web handling equipment.

Dimensions

Choose LF100A when a live-shaft flange tension sensor is required and the roller installation needs self-aligning bearing support.
| Good Fit | Live-shaft roller structures, flange-mounted installations and applications where shaft alignment compensation is useful. |
|---|---|
| Check First | Confirm shaft diameter, bearing arrangement, rated load, mounting space, output signal and side-frame structure before selection. |
| System Match | Use with compatible tension amplifiers, indicators, transmitters or automatic tension controllers according to the required output signal and control architecture. |
