Question:
I have two bearings, 25580 and 15123, however I need those bearings to have narrower inside diameters. 25580 will have 1.25 inch and 15123 will have 15/16 inch. Is this possible?

Hello Nicholas,
I do have bearing in the sizes you need as far as the Inner Diameter, but they will not match on the outer diameter.
The # 25580 has an ID of 1.750" and an OD of 3.265", the # 15123 has an ID of 1.250" but an OD of 2.441"
There are not bearings with a narrower inside with the same outer diameter, so they will not work in your hub.
What is your axle capacity? I think you might need new hubs to accomplish what you are trying to do.

Hey Nicholas, did you have a chance to check your axle capacity to see if new hubs might be the solution you need? I'm asking because it could help others who are trying to find the right bearings for their setup.
