Spieth guide gibs are flat guides with adjustable play.
Guide gibs FLW are ready-to-install machine elements that allow you to realise minmal guide clearance on your machines without the use of significant manual force. The process of designing and machining the contact surfaces on the surrounding components is straightforward, i.e. they are geometrically rectangular and parallel. The backlash is adjusted using a simple clamping screw, which is fitted on end face where it is easily accessable. This ensures that guide play can be corrected at any time if necessary.
