1. A spindle nut for a ball screw drive, comprising a fixed outer diameter (AD), a helical ball groove formed on an inner side thereof, an inner ring formed on an outer side thereof with a ring-shaped ball groove that forms, together with an outer ring and balls arranged in-between, a support bearing, the inner ring has a first stepped section that extends up to the ball groove with a fixed outer diameter (Si1) and contacts, on an other side of the ball groove, a second stepped section with a reduced outer diameter (Si2), the outer ring has a first shoulder that extends up to the ball groove of the outer ring with a fixed inner diameter (Sa2) and contacts, on the other side of the ball groove, a second stepped shoulder with an increased inner diameter (Sa1), a difference of the inner diameter (Sa1) of the second shoulder of the outer ring and the first stepped section of the inner ring with the fixed outer diameter (Si1) is greater than a diameter of one of the balls, and a difference of the inner diameter (Sa2) of the first shoulder of the outer ring and the second stepped section of the inner ring with reduced outer diameter (Si2) is greater than the diameter of one of the balls. |
