Helpful Expert Reply:

All hubs for 15-inch wheels in your 5-on-4-1/2-inch bolt pattern are shown on the linked page. These include both idler hubs for trailers without brakes and hub/drums for trailers with drum brakes. These various hub parts are compatible with axle weight ratings from a low of 2000-lbs up to 4000-lbs.

New hubs must use the same bearings as your old hubs in order for them to fit on your existing spindles. Older trailers can be a challenge when it coms to finding compatible replacement hubs.
None of the hubs for 15-inch wheels and with your bolt pattern use the same bearings you have.

Bearing part # 15123 is usually the outer bearing on a hub for a 6K axle. The inner bearing most often used with it is part # 25580 which has an inner diameter of 1.750-inches. You will be better off replacing the whole axle if your bearings are now obsolete.

Our main page for trailer axle kits is linked for your reference. We have both standard beam axle kits and also axle-less suspensions from Timbren, such as kit # A35RS545E, which is also a 3500-lb kit with hubs and electric brakes.
