Thk robot linear rotary bearing & mxl belt pulley LB520

Sorry- No International Sales-Including Canada
This is a unique THK linear bearing. It has 6 rows of re-circulating bearings that slide on the shaft and the bearing truck has a MXL 1.5" and sealed bearing on it. It is approx. 17" travel. Overall approx. length is 21". Great for that robot project requiring accurate linear and rotary movement? OR..just use as a regular linear bearing for your CNC machine. Really shouldn't matter that the truck has a bearing/pulley on it .Lock the pulley to the truck flange or just allow it to turn. Should affect a CNC machine either way.
