Redi-Rail® Slider Orientation

     Redi-Rail and slider image

Installing a Redi-Rail® slider properly is critical to the success of an application.  To ensure the utilization of the slider’s full load capacity and to reach its full life expectancy, follow these simple guidelines. 

  • A standard metric 3-roller slider has a center bearing that is mounted on an adjustable slide enabling preload.  The preload comes factory preset, but can be adjusted.  This roller will contact one side of the rail.  (Side “A” in the illustration)  The inch series has a fixed preload, and cannot be adjusted.
  • The rollers at each end are mounted to contact the opposite side of the rail and will carry the majority of the load.  (Side “B” in the illustration)

  • To identify which direction to mount the slider so that the two rollers designed to carry the majority of the load are oriented correctly, locate the arrows on the face of the slider.  Be sure to install the slider with the arrows pointing in the direction of the force or load being applied to achieve its rated load capacity. 


NOTE:  Some older versions of the Redi-Rail sliders have a similar design, but the load direction is noted by two indentations on the slider face instead of two arrows.
