This is called a “single start thread” screw.When two or more ball grooves are involved, such screws are collectively called “multi-start thread”screws.As the lead becomes larger, the spaces between ball gro Read More
  • [Ball Screw] Introduction about ball screws
    (Accuracy) The difference between the actual distance traveled compared to the theoretical travel based on the lead of the screw. The lead error for a standard screw will not exceed +/-.007” per foot and a premium grade screw will not exceed +/-.003” per foot. Lead error is cumulative based on the actual length of the ballscrew thread. Ref. Class 7-8 ANSI B5.48-1977. Lead charts describing incremental lead deviation offsets can be supplied (upon request). These incremental offsets can be input into motion controllers for lead error compensation. Read More
