An arrangement for sealing an opening in a plate (1) through which a shaft extends, the plate separating the "wet" and the "dry" zones of a packing machine from each other. In packing machines great demands are made on the tightness and durability of such shaft bushings, especially against strong washing agents, and the sealing assembly in accordance with the invention, therefore, has a flexible connection with the plate (1) and two O-rings (9,10), which are partly enclosed by two halves of a sealing assembly. Thereby, the O-rings are protected during washing as well as during operation. This design also produces a good sealing effect even when the shaft moves a little in radial direction during operation.
