  • Acme Screw VS Ball Screw: Which to Choose?
    There are several differences between acme and ball screws, and as in most cases the application will determine the type of screw used. The following article will discuss a few key points that will help you choose the appropriate screw for your application. Techno Linear Motion Systems - Automation
  • Selecting and Sizing Ball Screw Drives
    capabilities of various types of bal screws: Ball screw type. Accuracy. Precision inch. +/- 0.004 in/ft. Precision plus inch. +/- 0.0005 in/ft. Precision metric - T7 Accuracy Class. +/- 50 m/300m. Precision metric - P5 Accuracy Class. +/- 23 m/300m. Precision plus metric - P3 Accuracy Class
  • Ball screw basics
    The pros and cons of single and double-nut balls screws. Ball screws are preloaded using different methods, resulting in either two or four-point contact of load balls. And all preload methods, whether by using oversized balls, shifting pitch, or using a double nut, serve the same purpose
  • Journal Dimensioning for Machined Ball or Lead Screws
    Incorporation of Geometric Dimensioning and Tolerancing (GD&T) is useful in defining competent journal requirements in linear motion applications. Dependent upon how the journal / screw is dimensioned could lead to drastically different results. Journal Dimensioning for Machined Ball or. Lead
  • white paper: Shoulder Screws
    on the shoulder at moderate speeds. Springs are used on the shoulder to. preload components traveling axially along the length of the shoulder. The screws are used as axles for. rolling parts, as pivot points, as mounting pins and as guides in sliding elements. There are two basic shoulder screw
  • Keeping ball screws accurate and reliable
    receive substantial side loads. Use two indicators, or mark the high point and note the readings, then compare them to other journal and determine the difference. Nut squareness helps avoid cocking. When using V-blocks, a ball can be inserted into one center hole of the screw and the screw pushed against
  • Ball-screw basics: Debunking the myths
    screws on the market and the attendant flood of data from manufacturers, designers can have a tough time sorting out what truly affects ball-screw performance. Information often focuses on whiz-bang features that bring few real benefits, while more mundane but critical factors are missed completely
