How to Verify that the Bearking Kit # BK1-100 would fit Trailer Hub

Question:

Have a small trailer with Koyo bearings #L44643R, both inner and outer. Will your kit #BK1-100 be the complete kit needed? Or do races and seals come in different sizes to worry about too?

If the inner diameter of both of your current bearings is 1 inch then your trailer would take the # L44643 bearing. The R at the end of your part number shouldn't be an issue, but it would be worth verifying that your current bearing has the same inner diameter as the # L44643. The R should stand for high capacity.

For the # BK1-100 to work you will need to verify that your seal matches what comes with the kit. For that you would need to measure your current seal. If the inner diameter is 1.249 and the outer diameter is 1.983 the # BK1-100 should work well.
