thompson or thk???
I've worked on a machine for a friend.... early '80 cincinatti... round rods, split bearings - the bearings were shot and totally worn out. they would have lasted longer if there was a way to lube them. Rod diameter 2 1/2 inches, weight of just the machine table on them 7000 Lb. Machine was used for mold making = lots of back and forth movement!!!!

PS: I'm parting out the machine! (and it has almost new rods and bearings in the 'Y' axis!)
