Linear guides, cross-roller type

Linear guides, cross-roller type

Linear guides, cross-roller type

(OP)
Hi,

I'm working in metrology and automation and I'm looking for an alternative vendor for cross-roller linear guides.
At the moment I'm using Misumi (part no. crtd2035), their products are fantastic in terms of accuracy, repeatability and build quality with only one problem, they don't offer a pre-dowelled version.

The ball bearing linear guides can be got pre-dowelled but from experience they are prone to friction and occasionally jam up if the guide is mounted vertically and a load is extended out from it.

The cross roller type are perfect for my fixture it is a couple of hours work for the toolmakers to disassemble the guides, get dowel holes and slots into them and reassemble them and they don't tend to feel the same once they've been machined and put back in place.

I work in a factory in Ireland so any local suppliers would be great but I'm willing to deal with anyone worldwide as we're geared for Misumi's lead times which are generally in the region of 2-3 weeks.

All ideas welcome, thanks,
Emmet.

RE: Linear guides, cross-roller type

I couldn't see a way to take advantage of this advice with those particular parts, but I have noticed that Japanese machine tools tend to not use dowels or hidden/trapped keys, but to instead use gibs or shims bearing against external surfaces.
