Each roller may have two guide collars between which a groove runs and on which the roller may roll onto the blade bearing ring. A rail may be arranged on the blade bearing ring, and may engage in the groove between the two guide collars for each roller. Each roller may be retained on the blade bearing ring and on the adjustment ring exclusively via the guide collars of the respective roller.
