Expert Reply:

The outer race # 02420 that you found is used with the # 02475 bearing, which features an inner diameter of 1.250 inches. I recommend measuring the inner diameter of your exiting outer bearing with a digital caliper to make sure this matches.

When used as an outer bearing it is typically seen on 8,000 pound trailer hubs like the Dexter # 8-285-11UC3, which uses the inner bearing # 25580 (1.750 inch inner diameter). You can again take a few measurements on your existing hub to verify this is what you currently have.
