I have removed old bearings from a 60 y/o lathe and am having trouble finding new ones to match. They are marked Norma XF 135 on the bearing and I cannot find any online, and with the corona virus all the bearing dist. are not open. Does anyone know what the cross reference #’s are, or how I can find them, then I can order online. Thanks

Measurements? Typically in metric, although bore may not be. What lathe? 60 years is not that old.

Cheers,
Brad

PS: Does it have the following measurements? OD= 40mm Width= 12mm Bore= 3/4”

40mm od. 12mm w. 3/4” id. It’s a craftsman/king steely. It’s my age so that’s why I said old. Lol. Thanks for any help

6203-12 – basically a 6203 with a 3/4” bore. Some will label it as a 6203-3/4. I apparently was editing my previous post to add the measurements as you were posting :)

Cheers,
Brad

I INVESTED in good calipers a couple years back. For just over a hundred bucks, they are still on the same batteries. Using them, the prices of my bandsaw guide bearings dropped from $200 for a change of all ten to about $12. So to it went for my big lathe and other things. All I need is the shaft size, width and outer diameter and I save a pauper’s fortune.

Pay attention to descriptions for seals and such. For my bandsaw, I save the seals off old bearings, swap to ceramic and so forth. Interestingly, I packed one set with grease and it seems to keep the dust out better than when I went the standard route.

An uninformed question: Is it common for a bearing have metric OD and width but English ID? Anything is possible, but just seems odd.

Yes, it is very common to have Metric OD and English ID bearings. All of my machines are older “Arn”, my oldest machines date back to the early 1940’s, and they all are that way.

Thanks for all the info. They were 6203-12, metric and standard. Got them and installed already. Thanks again. GarenL.
