The Replacement Trailer Hub Bearing # 25580 is traditionally the outer bearing for a #99 spindle with the inner bearing # 28580. For instance the Trailer Hub and Drum Assembly - 7,000-lb Axles - 8 on 6-1/2 # 99865UC3 is a fit for your axle and is intended for the 7,000 lb axle which is what I assume you have. Both the bearings and grease seal are a confirmed replacement.
