Expert Answers about Bearing Buddy

  • Bearing Buddy Recommendation for a Trailer Hub Bore of 2-3/8 inches
  • Most likely the measure you took would have been 2.240 inches had you used a digital or dial caliper so the correct Bearing Buddy would be the part # BB2240. You might recheck the measurement you took to be certain that it is 2.240 inches.

  • Should Cardboard Be Removed Before Installing Bearing Buddy Bras
  • The cardboard is intended to help keep the shape of the Bearing Buddy Bras like part # BB23B when they are shipped, and should be removed before installing the bras on your Bearing Buddys.

  • Grease Cap for a Concrete Mixer with Inner Diameter of 2.375
  • The closest grease cap we offer to the dimension you listed that is designed for a trailer hub would be the # F001601, this is designed for a 2.333 inner diameter hub so it might be a little small. It is a press on style that does not have a rubber seal though. Since this is designed for trailer hubs I can't safely guarantee that it would work for you.

  • Are Grease Seals Supposed to be Curved to Match the Radiused Edge of Bearings
  • Every bearing we sell has that radiused edge that you are referring to so all of the seals we carry would work as long as you get the correct one for your setup. Grease seals do not seal the bearing so they do not have to match curvature. The seals seal the hub bore. Can you tell me what the bearing number is on your bearing? There's a glare in the picture so I can't see what bearing you have to match the correct seal to it. I attached a link to an FAQ article on wheel bearing backing...

  • Do Bearing Buddy Bearing Protectors Only Come in Pairs

  • Bearing Buddy grease Caps For Trailer With Hub Bore that Measures 2-1/2 Inches Diameter
  • The Buddy Bearing Bra, part # 23B you mentioned you have can fit many of the Bearing Buddy grease caps. The best way to find a Bearing Buddy that will fit your hub is to use a digital caliper like part # ALL641130 and take an accurate measurement. We have a couple Bearing Buddys that are close to the size you said your hub bore is. The first is part # BB2441SS. These fit a hub bore that measures 2.44 inches. The next size up is part # BB2562SS. This will fit in a hub bore that measures...

  • Bearing Buddy Recommendation for a Trailer Hub with 1.974 Bore
  • The closest bearing buddy we have would be the 1.980 part # BB1980A that it sounds like already tried. The next smallest size we have is the 1.968 part # BB1968 which unless you measured wrong would be too small. I am surprised you couldn't get the # BB1980A to fit. That should be close enough to make it work, it could be that you need to use a hammer and a board to lightly tap it into place.

  • Troubleshooting Grease Seal that Keeps Blowing Out on Trailer Axle
  • It sounds like your problem may be that you are installing too much grease into the hubs and that is why they are blowing out. If you are pumping your grease into your hub with a grease gun you should note that you should only continue to add grease to the hub until you begin to see the outer bearing move or you see grease seeping through the outer bearing. If you pump the grease slowly and rotate the hub, you should not blow the grease seal. Once you see the grease seeping through,...

  • Bearing Buddy Recommendation for a Hub Bore of 2.402 inches
  • For a Bearing Buddy designed to fit your 2.402 pilot hole on your hub you would want the # BB2441 or the stainless version part # BB2441SS. I attached a review video for you to check out as well. Pricing is below at the links.

  • Recommended Bearing Buddy Bearing Protectors for Hubs with Bore of 1.986-Inches
  • It sounds like you are looking for a Bearing Buddy bearing protector with a grease zerk fitting for your hub that has a 1.986-inch inner diameter. We offer two choices for your pop-up, either chrome-plated Bearing Buddy # BB1968 or the stainless steel version # BB1968SS. Both kits include two Bearing Buddy protectors and two flexible covers. Take some care when initially filling the protectors with grease to avoid over-filling that could blow out your inner grease seal.

  • Where to Measure to Pick Out Bearing Buddy
  • In order to pick out the correct bearing buddy you will need know the pilot hole of your hub. To do this, remove the wheel and tire and remove the grease cap from the center of the hub. Usually it is a metal cap that is just lightly hammered into place. Use a screwdriver to pry off the cap. Clean the grease off and measure the opening. The Bearing Buddies # BB1980A-SS that you referenced are for hubs with a 1.98 inch hub bore.

  • Replacement Vinyl Covers For Boat Trailer Oil Lube Hub
  • The vinyl covers we offer are designed for Bearing Buddies but you may be able to find one that fits your oil lube hub. We carry 3 different sizes so you will need to measure your hub to make sure you have a fit. The covers we offer are part # BB17B for 2 inch, part # BB19B for 2-1/8 inch, and part # BB23B, which is 2-7/16 inches. Each of these come with 2 in the package.

  • Bearing Buddy Availability for Hub Bore of 2.080
  • I wish we had a bearing buddy that would fit the hub you have, but none of the ones we carry will fit a hub with an inside bore of 2.125 (2-1/8 inches). You might try measuring the hub bore again with a digital or dial caliper to see if maybe you have a 2.080 hub bore. If that is the case you could use the # BB2080.

  • Is a Wheel Cap Recommended to Run Over a Bearing Buddy
  • The grease seal that comes with the Dexter Trailer Hubs and Drums # 84546UC3-EZ that you referenced is a double lip seal so you would be fine in that regard. Running a wheel center cap over a Bearing Buddy wouldn't be ideal as that would make the easy to use Bearing Buddy much more difficult since you would have to remove the rim. I would recommend not trying to fit one over it.

  • In What Quantities Are Bearing Buddies # BB2047 Sold
  • The product you referenced, Bearing Buddy Bearing Protectors Model 2047 # BB2047, are sold as a pair, enough for one axle. Each kit includes two Bearing Buddies and two rubber covers that fit over the bearing protectors after you've filled them with grease. If you have a tandem axle trailer you will need to order one kit for each axle, so that you get a total of four protectors and four covers. This kit fits hubs with a bore of 2.047-inches. I have linked an installation video for your...

  • Bearing Buddy Warranty Coverage
  • Bearing Buddies are covered by a lifetime manufacturer's warranty that would cover the replacement of the Bearing Buddies if they were defective, but not new bearings. I would refute what your mechanic tells you, however. I've seen countless trailers where folks have pumped too much grease into the hubs, and blown out the grease seal. To reach the seal, the grease would pass through the inner bearing. The grease has absolutely no problem reaching the inner bearings. You'll want to be...

  • How to Pick Out Replacement Trailer Grease Seal and How to Install Grease in Hub with Bearing Buddy
  • A common problem we hear with people with Bearing Buddies is that since it is so easy to add grease to the hub that they end up putting too much in and blowing out the grease seal. Replacing the seal would not be too hard, but we first would need to determine what seal you would need. To do that you will need to pull the hub and measure the inner diameter of the hub where the seal installs and then measure the outer diameter of the spindle where the seal rides. You will want to use a...

  • What is the Correct Bearing Buddy for Use on 2005 Airstream Classic
  • You can determine what type and size of Bearing Buddy to use on your Airstream trailer by taking a look at the current hubs. You will need to know if the hub bore is threaded or not and you'll also need to take a precise measurement of the hub bore diameter using a dial or digital caliper. You'll need to measure to the nearest thousandth of an inch, or three decimal places like 1.781-inches. Once you know your type and size of hub bore you can use the linked page to select those features...

  • Does Grease Seal have to Make Contact with the Inner Race for Bearing to Ride in the Right Place
  • A hub should only have one grease seal, at the back side of the hub, and it should be flush with the hub once installed. When everything is assembled and put on the spindle with the castle nut properly tightened down there should be only a few thousands of an inch of play meaning everything is in place. Races are pressed into a hub so they are not going to move and the edge of the grease seal may or may not make contact with the inner race. But that contact or lack of contact should...

  • Installation Method for Parts Included in Bearing Buddy Spindle Grease Seal Set # BB60002
  • The flat steel washers included in the Bearing Buddy Spindle Grease Seal Set # BB60003 are the first part of the 4-piece assembly to be installed on each spindle. These are followed by the L-shaped steel seal ring, then the O-rings. The actual large grease seal itself is installed into the hub's bore and then mates up with those other three parts already on the spindle. The linked video illustrates the last 3 items but does not the flat steel washers.
