Just a few notes on bearings for the Lathe and mill.

Headstock/Spindle take 1 each 6203RS and 6203ZZ bearings.

Mill CNC leadscrews take 2 608RS bearings each axis.

6203 = 17MM ID 40MM OD 12MM wide

608 = 8MM ID 22MM OD 7MM wide

RS= Rubber shield

ZZ= steel shield

The 608's are common rollerblade/skateboard size

Still not sure what the lathe crossslide bearing is.

Well Nick says the crossslide takes a 635RS 5x19x6mm Shielded Bearing

Wow Thanks Thats a good thing to know.

LOL ok Cool I found something I can belong to!


Hey Cool site love it. and I stopped by your website. Great to know that your there!
Might need help with the upgrade of my controller! email ya later!

Just a quick note about bearings. If you buy replacement bearings make sure you get a good (great) quality brand. A bearing that is good enough for a skate-board, etc. is not good enough for a machine tool. If in doubt about what your getting get them from Taig.

The spindle bearings in use in the CNC mill (perhaps all mills now) are Turkish made by ORS. These are tough, high-quality bearings. I friend of mine is trying to thrash the Spindle bearings as part of his PhD work on failure prediction. We have removed all lubricant from the spindle bearings and found that they will still cut aluminum for 13~15 hours straight before seizing.

Thanks Jeff I would always go with the OEM stuff just the way I am But hey thats is good to know and Thats kinda cool that your friend is testing these thingings.

Yeah, I'm amazed that he keeps beating the crap out of the machine and it just keeps chugging along. We can change the spindle bearings out in about 10 minutes now!

Well that tells people just how good these Taig products are man over the years I have beat mine to death as well and well timex and the pink bunny have nothing on the Taig!
