26. mpression load is a force that tends to compress or buckle a ball screw shaft If a compressive force is applied to a screw that exceed s its column strength the screw will bend Thus causing premature or permanent failure This can happen in either horizontal or vertical applications In some cases you may have to select a more rigid end sup port housing arrangement and or a larger diameter screw in order for the ball screw assembly to withstand your com pression load Refer to the Positioning Component catalog specification section for the maximum compression load for a particular Ball Screw model number If a sufficiently heavy load is applied to a nut with a long ball screw in a horizontal application the ball screw could buckle In a vertical application if a Fixed or Rigid motor driven housing is mounted below the ball screw the ball screw weight amp load weight could buckle the screw Therefore in a vertical application installing the motor driven sup port housing above the ball screw puts the ball screw assembly in a tension mode while the bottom end support bearing is free to float axially and is used only to guide the end of the screw By loading the screw in tension most of the time you avoid any compression load issues and only need to be concerned with the load capacity of the nut and end sup port bearings However in some vertical applications with the ball screw mounted in a tension mode you will have to be concerned about co
