Timken L521910-3 Tapered Roller Bearing Cup L521910 Precision Class 3

Timken L521910-3 Tapered Roller Bearing Cup L521910 Precision Class 3. These bearings are new old stock. I have them listed as used because the paper stuck to the bearing and left some spots. One has a clean race. Two have small spots in the race as well. I don’t think it could be used as class three. But might still be good for some old equipment repair. This NOS bearing was oiled and packed in a plastic bag before being returned to original packaging.
