As the title says, the guide is for a Chiron FZ 12 W, made in 1996, it's a traveling column machine, and there is some corrosion damage on Y axis rails, top ball row only, at around last 100mm in Y- direction (towards operator)
tried googling for NSK ball linear guides, and the ones I could find didn't have this row configuration, so I was wondering if that could be some special order product made for Chiron, or just an obsolete design, it is difficult to see in the picture, but the screws are covered with a spring steel strip that is spot welded at the ends to the rail
2nd picture is of the truck, the only markings I've found so far on them are the ones in the picture - 55-059KL
and a pic of damage
