    What are the types of ball nuts mean?

    Hello. More or less I know about ball screw, but I am defenitly uncomprehending with type of ball nuts like this.

    I guess that
    S - single
    D - double

    I have checked on a drawing the number of holls, flange edges dia's but haven't found difference.

    Where can I read about ball nuts?

    P.S
    Even in this, very useful article http://www.designworldonline.com/art...ew-Drives.aspx isn't mention about abbreviation

    Thank you in advance.
