摘要： In a recirculating ball nut for a ball screw drive, having a base body which includes at least one recirculating ball track, the base body is a forged component and the recirculating ball track is manufactured by a cutting manufacturing method. A further subject matter of the invention is an assembly for a ball screw drive of a power steering, having a belt pulley and a recirculating ball nut according to the invention, the belt pulley being connected to the recirculating ball nut so as to be non-rotatable relative thereto. A further subject matter of the invention is a method of manufacturing a recirculating ball nut.
