Specially developed dampers for drive or PTO transmissions. The dampers are bolted to the flywheel and drive the transmission input shaft. During driving operation the entire engine torque is always taken up by the coil springs.
Version with bearings for a drive shaft with universal joint is possible.
Due to the special requirements for PTO drive trains, the required torque is only passed through the springs when in no-load operation. The damper is bridged when it is under load.
