1 1/4" and 1 3/4" Bearing kit
Inner Bearing Number 25580
Outer Bearing Number 15123
Includes Zinc Plated Cotter Key
This Bearing Kit is used on 5200lb Trailer Axles. These Axles are typically seen with 15 inch and 16 inch trailer tires. You will notice by looking at your trailer hub that the back side, (the side on the inside of the trailer) is larger than the front side (the side facing the outside of the trailer). Also, when removing your trailer hub, your spindle, (the part that the bearings ride on) is tapered, meaning larger on one end and smaller on the other.
This Bearing Combination is fairly common, and accommodates most 5200lb axle configurations, but not all. There is another 6 lug bearing combination which is fairly common to see on modern trailers, which uses a 67048 bearing instead of the 15123 in this kit. Because of this, and the many other possible bearing combinations your trailer may have, we highly recommend removing your bearings and seal to check and verify that this is the bearing kit you need. If you notice something odd or different give us a call and we will get you taken care of!
