Packing system for use with a rotatable shaft and device with rotatable shaft which comprises a packing system of this nature. The invention describes a packing system for use with a rotatable shaft which is guided through an opening is a partition between two chambers is which different pressures may prevail. The packing system comprises at least one angular packing which can be arranged around the shaft, a gland as well as clamping means for moving the gland uniformly towards the partition is the axial direction, compressing the packing against a stop. The stop comprises a face which extends in the radial direction with respect to the shaft; at least part of the stop comprises a component which may be fixedly connected to the shaft or forms part of the said shaft. Alternatively, the bearing surface may be formed partly by a face of a projection on the shaft and a part of a projection which forms part of the partition. The invention also describes a device which comprises a rotatable shaft which is guided through as opening in a partition between two chambers, sealing being provided by means of a packing system according to the invention.
