...built a lot of custom robotics for Aerospace, Nuclear, many others and was always around linear slides but buy the time this technician got them they were usually hooked to ball screws etc.? I usually did all the electrical/electronic/sensor/motors blah blah.....fun as?heck, I was always the one to throw the switch?then the?Nerds and I would put it through the paces....(prepare to duck)
I have a bunch of NSK lgy25 mm slide units that seem rather tight, tight enough that it seems that 4 of them hooked to a 3/8 16 with a NEMA 34 might have too hard of a time pullin and pushin....that is a heck of a good gear ratio but still?
I have one set that seems right, (slide easily with my fingertips)?they may be a little dry though and 3 sets that are pretty tight (grab ahold and physically pull)....I tried them on different rails that I got from different places...took the blocks apart and they all look new with no wear...
They are a double row bearing also, so pretty heavy duty......I'm thinking of taking the outer row of balls off and running with one row....it won't hurt with the weight I'm carrying on a Y axis.
When you dig through the junk yard, you get what you get!!!!
