Expert Reply:

Since the current hubs on your trailer use the # 25580 inner bearing, there are a few possible options for the exact outer bearing replacement. Most likely, the outer bearing you need will be # 14125A, # 15123, or # LM67048. These all feature the same 1.250 inch inner diameter, meaning they will all fit the spindle on your trailer. However, they each will have a slightly different outer diameter, which is what needs to match up with your current hubs.

Since you cannot read the number stamped onto the bearing, you will just need to measure both the inner and outer diameter of the outer bearing to ensure you choose the correct replacement. I recommend using a digital caliper like # PTW80157, as the measurements need to be exact. Since there are a few possibilities, you will want to measure the inner and outer diameter on the existing grease seal as well.

If you are able to give me these dimensions, I will be happy to recommend the correct replacement bearings and seal for your trailer. I have attached a couple articles on trailer bearings that you might also find helpful.
