These are unlikely to be found in 'our' workshops, but i thought folks might find them interesting.

Handy to know, a mate wants an image rotator making for his robotic observatory, could be just the thing (depending on price).

Well that supplier says they design the bearing for each application individually so I suspect they are outside his range!

The concept isn't new, but definitely clever.

I have an elderly Graul tool and cutter grinder, thought to be Swiss made, on which the toolslide is guided by a long row of captive balls in a linear brass spacer running between hard wires in pairs on either side. It is very free running, easy to adjust for taking up any wear and equally easy to clean if it gets contaminated in any way. I found it in a British Rail sale at their workshops in Darlington over 20 years ago and it was very definitely old then.

The movements for the other axes are rather more conventional.
