A cylindrical mounting sleeve suitable for mounting a rotor assembly on a shaft, said cylindrical mounting sleeve comprising a hollow cylindrical portion having a length L and an inner surface with a radius R, said cylindrical mounting sleeve further comprising at least one elongated protrusion formed on the inner surface, the elongated protrusion having a height H. The path of the elongated protrusion forms an angle A to the longitudinal centre axis of the hollow cylindrical portion, said angle A being greater than 5 degrees and less than 70 degrees. In this way, a mounting sleeve is provided which reduces the damage during mounting of the sleeve on the shaft. This reduces imbalance in the rotor assembly. The invention also relates to a rotor assembly comprising such a cylindrical mounting sleeve.
