Recommended Trailer Axle Bearing Dust Cap Compatible with 2.10 Inch Hub

Updated 09/03/2024 | Published 10/15/2018

Question:

I have a homemade trailer that was missing an axle bearing dust cap, previous owner had a cut coke can over the outer diameter of the hub. 1.98 dust cap is too small. a 2.44 is way too big. It is hard to get a good measurement but I think I need one about 2.10inch do they make such a thing?

That is not a typical grease cap/dust cover size, however we do have the Bearing Buddy Bearing Protectors # BB2080 which measure 2.08 inches. These caps actually make maintaining the bearings much easier and more convenient as well. I've attached a couple videos to assist. The precise measurement using a digital caliper that can measure to the nearest thousandth of an inch is best.

I have the same axle measures 2.1 in. And the 2080 bearing buddy’s are to small. Can not find a cap anywhere !

@NickB if you have a 2.10" hub bore that is slightly larger than the 2.080" hub bore the # BB2080 fits. Keep in mind, you will have to drive them in since they're designed to be tight, so that may be the problem.
