You will need to measure the inside diameter of the bearing, that is the most critical measurement. You would need to use something like a digital caliper because it is measured in thousandths of an inch. A ruler or a tape measure wont work.
In this case, if we measure the inner diameter of this bearing, it would be 1 inch.These bearings are lubricated by wheel bearing grease or in some cases, it would be oil. The wheel bearing would consist of three components. The cone, or the inner ring, that the bearings would roll on the tapered bearings themselves, right here and then the cage or the roller retainer that the roller bearings are attached to. There is one other piece that is required and that is the bearing race that the bearing would sit into and rotate in.

The important measurement on the bearing race is the outer diameter, which for that part number would be 1.980. That should do it for review on part number L44643. .
