Video Transcript for A Closer Look at the Replacement Bearing Buddy Bras

Hey guys, it's Randy here at etrailer.com. Today we're going to be taking a look at the replacement bra for the Bearing Buddies. Now, this is going to be the larger size. This is outside to outside dimensions, here are going to be two and 1/8 of an inch. These are just spacers to keep them in shape. Generally, it's going to be, as you can see here, a hollow cap.Now, this is going to be a vinyl cover.

You're probably used to seeing, especially if you're looking for the replacement or maybe you've bought a new trailer and these we're missing on it. Basically, your Bearing Buddy sticks on the end of your hub. This is just going to slide over the end of it. It keeps everything contained, and it's going to help keep any excess grease contained within rather than it getting that rotational energy and slinging out on your tires.Now, as far as the models it's going to fit, again, the key thing to know is if you measure your Bearing Buddy and it's near two and 1/8 of an inch outside to outside, this is going to be the replacement. So that covers the 1980, 1980SS, 1980A, 1980A-SS, 1938, 1938SS, 1968 model, 1968SS, 2047, 2047SS, 2080, and 2080SS.It's going to be an excellent way to keep that grease from being slung around, and it also keeps moisture from getting in there.

It keeps dirt from getting in there, and it just helps to ensure your Bearing Buddies are going to last for a very long time and keep your bearings in there packed full of grease.There's also going to be instructions here, as far as how to check the levels. So if you don't know exactly how a Bearing Buddy works, it spells it all out right there for you exactly how to just push the piston. If it doesn't rock, add a little grease. If it does, you're good to go.But all in all, just be an excellent way to get those protected and also protect grease from being flung out all over your wheels and tires.

Our existing Bearing Buddies did not have Bras so I figured why not get them for all of them. They work great and keep everything dust free.

These are life savers! - no worries of over filling your bearings ever again ( these are just the caps- be sure to get the kit if you need them).

Every boater knows about Buddy Bearing and Bras. You can't beat the best and you can't beat the price and service at eTrailer. Best site on the web for trailer parts and supplies. And, the fastest shipping too. I love shopping online at eTrailer.

I was gifted a 14 ft. aluminum boat and trailer from my brother in law, which was over 50 years old. I wanted to redo both and bring life back into them. Etrailer has been there to help me achieve my dream with multiple quality parts that I needed. Their help over the phone when needed was outstanding and professional. Products shipped and arrived within just a few days. Thank you Etrailer for helping me make this project come to life.

The trailer looks fantastic, Keith! It's so awesome to hear stories like yours. Is there anything else you need to do to the trailer/boat or are you all finished?

Working great !



by:

I have been working on a boat and trailer that I got in a government surplus auction. The trailer is a triple axle and needed quite a bit of work. I replaced one axle and the brake lights. I am in the process of replacing all of the brakes, tires, bearings and seals. I am about half way done with the trailer and so far I have been very happy with the parts I have received from etrailer. I have not been able to road test them yet but installation has been great. I intend on getting a majority of the parts I need to finish the project from etrailer. The video overviews and installation instructions have been very helpful. Looking forward to sharing more pictures when the project is done.



by:

Second set if these I've used. First was on my utility trailer years ago. This set is on my home built log splitter. The first time I towed the splitter I suffered from a bad inner seal that spewed grease all inside the one wheel rim. I was 150 miles from home, deep in the woods. Had to pull the wheel and repack the axle with grease to make it home. Found a welding spall on the axle that chewed up the seal. Removed the spall, polished the seal surface and put on a new seal. Then I added the Bearing Buddy's to make sure I kept things lubricated in the future. They do the job and provide peace of mind.



by:

Well, this will help keep the rims cleaner. I've used these before and they work great.



by:

Perfect fit thanks !!!!!!!



by:

Thanks for reaching out. The bearing covers work great.



by:

Fit my grease buddies perfect



by:

Perfect fit on my boat trailer. I had previously bought 2 sets of dust covers that would not fit and stay on during trips to lake. Thank you for speedy delivery and order response. Great product



by:

Work just great. Tight fit, no seeping of grease.

  • Determining Which Replacement Bearing Kit Fits 2004 Eagle E20-50TTBW Tandem Axle Boat Trailer
    I'd be happy to help you find bearing kits for your 2004 Eagle Boat Trailer Model E20-50TTBW, but we have no database to look this kind of thing up so you'll have to do some measuring. You'll need to remove one of your hubs and try to identify the bearing numbers, or more than likely use digital calipers # PTW80157 to measure the locations of the spindle shown below. Most tandem axle boat trailers like yours use 3,500lb axles so more than likely you'll need bearing kits # BK2-100, one...

  • How To Identifying A Replacement For A Missing Bearing Buddy
    From looking at the pictures you included, it does look like you will need the Bearing Buddy # BB1980A (Chrome Plated) or # BB1980A-SS (Stainless Steel). However, both of these are designed to fit a 1.980" hub bore that is commonly found on 2,000-lb, 2,500-lb and 3,500-lb Dexter axles. With that being said, I strongly recommend measuring either the bore of the hub, or pulling the existing Bearing Buddy off to verify its size. The 19B rubber cover ( # BB19B) can fit 5 of the Bearing Buddy...

  • Precision Digital Caliper to Measure Hub Bore to Select Correct Bearing Buddy Bearing Protector
    Bearing Buddy protectors are made in lots of sizes, many of which are very close to one another in their diameter. It is really necessary to use a more precise measuring device on the hub's bore unless you know the part number of the one that was lost. You might check the remaining one for any identification. There are two sizes that are close to your 2-9/16-inch dimension, 2.562-inches and 2.717-inches. Bearing Buddy parts that fit hub bore diameter 2.562-inches are either part # BB2562SS...

Part # BB17B has an outer diameter of 2 inches, and part # BB23B has an outer diameter of 2.441 inches (this would be the second most likely one for you to use). You will need to measure your current bra to determine which you would need.

  • Bearing Buddies that Measure 2-1/8 Inches in Outer Diameter
    When selecting bearing protectors the measurement needs to be as accurate as possible so you will need to use dial calipers. We have a digital set we use here for precise measurements. Since 2.24 is too large and 1.98 is too small the size in the middle is 2.08 like # BB2080. For replacement bras you would use # BB19B.

  • Selecting Bearing Buddy Grease Cap Covers for 2-Inch Diameter Bearing Buddy
    The Replacement Bearing Buddy Bras Model 17B, part # BB17B, will fit on Bearing Buddy grease caps for hub bores from 1.781-inches to 1.810-inches. 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. This bra has an outer diameter of 2-1/8-inches. I suggest part # BB17B since it will provide a more snug fit.

  • Replacement Bearing Buddy Bras for Bearing Buddies with 2.13 Inch Outer Diameter
    Based on your measurement of 2.13 inches it sounds like you will need model 19B # BB19B. These have an outer diameter of approximately 2-1/8 inches. They will be easier to put on if you leave them out in the hot sun for a little while. It makes them more pliable. The next size up would be way too big and the next size down will be too small.
