What can I say? They cover my bearing buddies and stay secure. Before these I would have to remove my camper wheels because there was a plastic hub that inserted from inside the wheel to cover my bearing buddies. Now I have access anytime I feel the need to add some grease.

The aging dual axle boat trailer I bought had Bearing Buddy brand caps on one side and some other type on the other. One of the "others" is split and the second looked as it might not last long. Other brand replacements did not seem look and feel as durable as Bearing Buddy so I ordered two. Packaged they had a disk insert to maintain shape, they fit snugly, and seem durable.

These fit my stainless steel bearing buddies perfectly. The trick is to measure the diameter of the bearing buddy and make sure you are ordering caps made for this diameter. This is important because stainless steel bearing buddies come in two, slightly different diameters.

The dust covers looked to small so I thought that I had ordered the wrong size. However, I tried one and it is a very tight fit, which is probably a good thing for a boat trailer to keep water out of the hubs. Hope I can get them off to grease the bearings.

Gotta have the real bearing buddy caps/ bras. The cheap knockoffs always end up flying off. These have been dunked in and out of some nasty boat launches, hundreds of miles on gravel roads and they’re still on.

I have used these on all my trailers and ordered these for a new to me PWC double trailer. While I never use bearing buddy's, their dust covers over the metal dust cap/rubber grease cover plug is just another layer of defense in keeping water and contaminates out of your bearings and hubs. And they look nice. Cheaper here than anywhere and shipped fast!

These units come with the bra covers included, and they installed easily. I used a block of tropical hard wood to protect it, then I hit it on with a small sledge hammer. This is one of those quick easy jobs you can do that will have long-term implications for the useful life of your trailer. They're of good quality, and I'm proud to have it on my rig. I packed them with a waterproof green grease, because of the climate where I live. Initially I tried to order from Amazon, but they didn't ship to Hawaii, which is plain awful. Thankfully eTrailer shipped ultra-fast and for a reasonable price. Will be returning here from now on for trailer stuff.

First off I want to say, if you use your trailer a lot and do some serious highway driving, you would be foolish not to have "Bearing Buddies" on your hubs! The covers on mine were old and getting loose. These fit perfectly and will help me get on down the road without worrying about my wheel bearings.

I've tried several of the retail stores in my area for the smaller sized bra for my utility trailer. Couldn't find. Decided to try on line. ETrailer had three sizes and lots of Q&A's regarding sizing which was most helpful. Measured my hubs, ordered and fit as advertised. Perused rest of web site and found other RV items for my travel trailer. This is a whole lot easier shopping than driving across the county to nearest store and then trying to locate needed item. I'll be back.

These caps will have an outer diameter of close to 2-inches. Because these bras are made of flexible vinyl they will fit multiple sizes. The next size up is part # BB19B.

view full answer... - Is It Normal For Grease To Appear Under Bearing Buddy Bra/Covers? It is normal for grease to get inside the Bearing Buddy # BB1781 underneath the Bra # BB17B. As the grease heats up it can expand and will push out the Bearing Buddy so it will not damage the grease seal on your hub.
view full answer... - Are Replacement Bearing Buddy Bras the Same as Dust CapsYes, replacement Bearing Buddy Bras are the same thing as dust caps, they simply replace the cover that came with your Bearing Buddy or bearing protector. You can measure the diameter of your Bearing Buddy/bearing protector and match up the correct Bearing Buddy Bra. - 2 Inches: Replacement Bearing Buddy Bras - Model 17B # BB17B - 2-1/8 Inches: Replacement Bearing Buddy Bras - Model 19B # BB19B - 2-7/16 Inches: Replacement Bearing Buddy Bras - Model 23B # BB23B
view full answer... - How to Measure Bearing Buddy to Pick Out BraWhat you can do is measure the outside diameter of the Bearing Buddy with a digital or dial caliper and then you can pick out a bra for it based on that. So if yours measures right at 2 inches in diameter for example you would want the part # BB19B. If it's 1.7 inches you would want the # BB17B or 2.3 inches part # BB23B.
