GLOSSARY AND TECHNICAL DATA (continued) Screw Inertia GLOSSARY AND TECHNICAL DATA (continued) Anti-Backlash Life Screw Size Screw Inertia Anti-backlash life is defined as the nut’s ability to compensate for wear while maintaining its zero backlash properties. Above life data is based on 30% of dynamic load rating. Life will vary with loading, operating environment and duty cycle. The longer screw leads generally provide longer life. Surface Finish 304 Stainless Steel (options available) Better than 16 micro-inches (0.4 µm) Polyacetal with Lubricating Additive Other materials available....

CRITICAL SPEED: ACME INCH SCREWS CRITICAL SPEED: METRIC SCREWS TO USE THIS CHART: Determine maximum travel rate required. Determine screw length L. Find point at which travel rate and screw length intersect and select a screw above and to the right of that point. Curves are alternately broken and solid for ease of use. The line type has no significance. NOTE: Maximum Speed is limited to 80% of the calculated Critical Speed. See pages 12-13 for reference description on A-B-C-D end fixity. Metric to Inch Conversion: 1 Newton = .224 lbf NOTE: Curves are alternately broken and solid for ease of...
