Compression-column load is a load that tends to buckle or compress the screw shaft. How To Use Chart: 1. Determine maximum compression load (lb.) 2. Determine slide length. (“L” dimension) 3. Determine end fixity and slide designation (2RPS and 2LRPS) 4. Find the point at which load and length intersect 5. Select a slide above or to the right of the intersecting point Note: Applies primarily to vertical applications.
