Today we're going to review part number 15123. This is the Axle Technology replacement trailer wheel bearing. This is the outer bearing. These replacement bearings are high-quality, tapered, roller bearings designed for high-speed use. All bearings will have an industry standard number stamped on them, regardless of the brand. To replace the bearings on your trailer, what you would want to do is look on the inner ring, and there'll be stamped a number.
Like in this case right here it's 15123, which is the part number for this bearing. Depending on the brand of bearing you have, it might have a different number, but if you just get the part number you would have and give it to us, we'll be able to cross-reference it and get you the correct bearing you would need. The other way would be, if you do not have the bearing number, you would have to measure the internal diameter of the bearing, which is this part right here. To do that correctly, you do need to use a digital caliper, which would give you a reading in thousandths of an inch, because the measurement is in thousandths of an inch. A regular ruler or a tape measure would not work.
If we do an internal measurement, for this one it would be 1.250, internal or inside diameter. This bearing does consist of three parts. Basically, the inner ring or the cone is right here in the center that slides over the spindle, the roller bearings, which will rotate all along here, and then the cage or the roller retainer that the bearings are held into, or held with. There is one other piece that is required, and that is the race, the bearing race, and that is the part that it would be pressed into the hub, that when the bearing is installed would set into the race and rotate in the race. That is sold separately.
For this bearing, the part number of the race would be 15245. The bearing race, the critical measurement would be the outer diameter, and for that, part number would be 2.441. A bearing does use wheel-bearing grease, or sometimes oil, as a lubricant. That should do it for a review on part number 15123.
