I can certainly help you determine the correct bearings and hub for your boat trailer. Unfortunately I wasn't able to find out much about your trailer, and could not find the correct bearings and hubs to replace the existing ones on your trailer. We offer replacement bearings individually, as a kit, and as a kit with a replacement hub.
The best way to determine the correct replacement bearings is to take the hub off of the trailer and find the part number on the existing bearings and seals. If the bearing is too damaged, or you cannot find the part number, then you will want to use a digital caliper, like # PTW80157, to measure the bearing seat for the inner and the outer bearing. This will help us determine the inner diameter of these bearings.
When replacing the bearings, you will likely also need to replace the grease seal. If you cannot find a part number on the seal, you will also want to measure the seal seat to have an idea of the seal inner diameter. To find the seal outer diameter, you will want to measure the hub where the outside of the grease seal sets.
I have attached two photos showing where you will want to measure for your bearings and grease seal. These photos also have information about the location of part numbers, bolt patterns, and bolt patterns.
To choose a replacement hub, you will want to take into consideration the weight rating of the trailer axle and the bearings and seal needed to fit the spindle. Typically, you will want to keep the wheel bolt pattern on the hubs the same as well.
If you can let me know what the exact measurement is on the inner bearing seat, outer bearing seat, and grease seat on the spindle and hub, I will be happy to determine the correct replacement bearings and seal for you. If you're also interested in replacing the hub, the axle capacity and wheel bolt pattern, as well as if/what type of brakes the trailer has will be helpful.
I have attached links to our hub and bearing product listings. I have also attached a help article on replacing the bearings, races, and seals on a trailer hub and an article on determining the hub's wheel bolt pattern for you.
