The FH series, manufactured by Ringspann, is a type of housing freewheels specifically made for stationary arrangements in multi-motor drives. The series consist of a hydrodynamic roller lift-off. The device is mostly used wherein assemblies can be driven from two or more motors or turbines. They allows a plant operation simultaneously if one of the energy sources fails. The plant operation can also be done in case of partial load operation. The device is enclosed with freewheels for stationary arrangement. They have input and output shafts. The device has a maximum of 24 to 405 Nm.

The series can be used on overrunning clutch if the speed and the driving operation are the same.
