    SINGLE START AND DOUBLE START NUT

    Hi, I am newbie

    I've got problem with my ball screw and nut set I bought from a supplier, I cannot install nut into ball screw, it stuck in the first lap then balls drop.
    The screw is 20mm diameter, 10mm lead double start, but the nut has only 1 groove with 1 return, is it single start nut?
    Is there any case a single start nut can match a double start ball screw?

    Sorry I am not good at English, thank you very much

    I think a 20mm lead single start could work with a 10mm lead double start, but could only transmit half the force (one of the starts wouldn't be used.)
