Slide Gib

Straight Gib Adjustment

1.Loosen gib screw nut on each gib adjusting screw. 2.Adjust screws starting with center and work outward. 3.Tighten all gib adjusting screws (alternating from end to end) sufficiently to ensure complete bearing contact between saddle and guide rail.4.Loosen each gib adjusting screw and retighten eachuntil it meets resistance.5.Tighten gib screw nut on each gib adjusting screw. 6.Verify alignment by indicating side-to-side movement. 7.Cycle slide to assure free and smooth motion. Straight gibs are standard, and areadequate for most manual feed and powered feed slide applications having low duty cycles.Tapered gibs are optional and should be considered on most power applications having high duty cycles and/or precision positioning applications.Single tapered gibs are limited to saddless with lengths no more than twice the saddle width. For lengths greater than twice the saddle width, two opposing tapered gibs must be used.As standard, the gib is located on theright side of the slide, when viewing from the drive end.An exception to this is when the slide is mounted sidewall, the gib should be on the bottom.Also, the gib should always be on the side opposite the direction of loading.The following is offered as a guideline to properly adjust the gib.Gib adjustment may vary for each particular application with final adjustment determined by the customer to assure proper performance.

Tapered Gib Adjustment

Note: Slides with tapered gibs have two opposing taperedgibs that must be adjusted simultaneously.1.Remove gib covers.2.Loosen and remove gib adjusting screws on both ends of the saddle.3.Remove spacers. 4.Replace gib adjusting screws and tighten sufficiently to ensure complete bearing contact between saddle and guide rail.5.Loosen gib adjusting screws and retighten until theymeet resistance.6.Measure gap between the saddle and the bottom of gibflange and grind the spacers the respective dimension.7.Remove gib adjusting screws, replace spacers, replaceand retighten gib adjusting screws, replace cover.8.Cycle slide to assure free and smooth motion.
