Expert Reply:

The # L44649 bearing referenced in your question features an inner diameter of 1.063 inches and is typically used as the inner and outer bearing on the BTR spindle or the outer bearing on a # 84 spindle. I was not able to find any information on the L44949 bearing that you also mentioned. If you are reading the number stamped onto the inside of the bearing, it's possible that it is simply worn enough that the numbers are difficult to decipher.

To be sure, you can simply take a quick measurement of its inner diameter with a digital caliper like # PTW80157. If it comes out to 1.063 inches, then it is actually the # L44649 bearing.
