We carry many sizes of trailer idler hubs and hub/drums with the popular 5-on-4-1/2 wheel bolt pattern. You can see all of them on the page I linked for you.

On the page are filters you can click on to choose your required features. You want to match up the hub weight rating to your axle's capacity to ensure it can handle the weight on it. Just click on your axle capacity; usually you can find this on a sticker or plate on the axle itself, or on the trailer's main sticker if it lists the axle rating.

The best way to go is to pull one of your hubs to get the bearing part numbers. The part numbers appear on the bearings as shown in the linked image. Once you know the inner and outer bearing it is simple to click on those parts to then see all hubs that use them. Matching the bearings ensures the new hub will fit on your spindles.

For example, if your 4.80 tires are on a 12-inch rim and your hub uses two of bearing # L44643 you can use a hub like # T4084600042 which works on a 2000-lb-rated axle.
