Hi cncuser, if you're using a 3/8" leadscrew then you wont be transmitting any significent force to worry about. I'd be more concerned about the fact that you are using a bronze bush with two thrust washers to do the job of end location. A better solution would be two angular contact bearings in back to back configuration which will do the complete job and if sealed in a housing would take care of lube problems as well. |
