I wish I could tell you based off of the picture you sent in what bearings work with your spindle but if you don't have numbers on your bearings then the next best thing is to take a digital caliper and measure where each of the bearings and the grease seal sit on the spindle to the 3rd decimal (for example 1.234).

Replacement bearings and seals need to fit exact which is why it is important to use either the part numbers or the caliper. If you know the weight rating of your trailer axle that can help too as there are typical bearing/grease seal fits but it isn't always a guarantee.

I have attached a photo showing where you need to measure on your spindle as well as a link to our selection of bearings and seals that you can filter through. If you let me know what those measurements are I can help you find the correct replacements.

One other thing you may want to consider is changing out your spindle as well. From the picture you sent in it has seen better days and if there are any grooves, dents, or chips where the bearings or seal rides then that can cause premature wear for a few different components.
