  • What's the purpose of a double ball nut? - Linear Motion Tips

    Oct 02, 2015 · The geometry of double nuts differs from that of single nuts in that double nuts, when preloaded, produce two-point contact between the balls and raceways, whereas preloaded single nuts have four-point contact. This four-point contact causes differential slip, or partial sliding, which increases heat generation and results in premature wear.
