Take-up and Spindle Thrust Bearing Kit for 9" & 10 k South Bend Lathe. Includes: 1pc high quality ball thrust bearing, 1 set high quality needle roller thrust bearing, and 1 pc .032" commercial washer/shim. I have been running this upgrade for about 5 years and have had no issues with it. I haven't needed to adjust the take up nut at all.
