Bearing Buddy Bra 17B - 1 Pair USA-Made, Black Vinyl Covers - Protects and Keeps Grease Off the Trailer Wheels - Fits Models: 1781, 1810

Fit is great and works as it should. Just make sure it's the right size for your application. There are numbers on the buddy itself that will get you the size needed.

Unable to identify the manufacturer or model number of my boat trailer bearing protectors, the Bearing Buddy fitment chart provided no help (officially, 17B fits Bearing Buddy models 1781 and 1810). Instead, I measured the outer diameter of my protector with a digital caliper (2.00") and relied on the advice of some other reviewers to determine proper fit. I was glad I did. The instructions on the package advise to, "Simply press the bra on over the Bearing Buddy and you are all set". Not quite that easy, but they WILL fit with a bit of effort. I found that a heat gun or hair dryer helps soften the material while a single drop of dishwashing liquid smeared around the inner lip of the bra helped ease it over the bearing protector. I also used a toothpick, like a tire iron, to stretch-on the last bit of bra around the protector, and to provide an outlet to press out air trapped within the bra prior to toothpick removal. A firm, tight fit was the result... better than too loose.

Well they fit hopefully they will keep the grease off the wheels 👍

Nice tight fit to keep water out

Pros for this product is that they seem very well made and that they will last for years!. I guess a con would be it took about 15 seconds longer to install because it's such a tight fit. Just use a small screwdriver to help it on and you'll be good! Just did over 500 miles so far and both kept the grease in and water out!

I recently bought a trailer that has Bearing Buddy's on it, but the covers were missing. I cleaned out all the old grease, completely disassembled the bearing buddy's, repacked the bearings, and put these covers on to keep the new grease clean.

I lost one of my bras on my boat trailer because I did not press it on far enough and I bought this to replace it. The 17B bra fits my bearing buddies just fine. I am not sure which model BB that I have so I measured the outside of my BB and the opening of the other rubber bra that I have on the other bearing. Both of them were at 2". I used a ruler, not a caliper. I thought that the 19B would be the cap that I needed looking at the product description but I saw reviews saying that the 19B was too large. So, I took a risk and got this one. It was quite tight getting it on the first time. Perhaps it is for a smaller model? Idc because it stretched and creates a nice seal!

The product itself arrived quickly and was made well, for a plastic cup. However, I ordered the wrong size (totally my fault).

A little thinner and shorter than the one that came with the Bearing Buddies but fit is good and should do the job
