Bearing Buddy Operation

Replace your existing grease cap with a Bearing Buddy to ensure a safe, easy way to monitor and control the level of grease in your axle hub. To adjust the amount of grease in the hub, use a grease gun to add more through the appropriate fitting. Adding grease moves the Bearing Buddy spring-loaded piston outward 1/8".

The O-ring inside the barrel of the Bearing Buddy maintains a seal from the outside. The interior of the Bearing Buddy is pressurized, preventing water from entering the barrel and diluting the grease.

An automatic pressure-relief feature is built into the Bearing Buddy. When the device is full, grease will seep around the edges of the piston and into the barrel. This prevents overfilling that can damage the inner seal.

You can manually check the grease level in your Bearing Buddy by pressing on the edge of the piston. If you can rock or move the piston, the hub is properly filled.

Your product arrived on time and undamaged. It installed exactly as described in the literature. I am very pleased with my new Bearing Buddy's. As a side note I noticed a small amount of chrome machining debris inside the hub of the housings. It was easily cleaned out with a rag before installation. These Bearing Buddy's are installed on a 32 year old utility trailer I am refurbishing. Although the trailer is small (4 x 8) it has a 5000# axle and has seen some pretty tough use. Ive attached a pic of the trailer undergoing refurbishment along with a couple of pics of the installed Bearing Buddy's. Excellent product and service! 107659

Whats to say the Bearing Buddy's are great. Do exactly what they are supposed to do and are very good quality equipment that will last for years. E trailers shipping on the other hand and customer support rates in the poor category. Nothing but excuses and canned reply's. Don't pay for the three day shipping it is a waste of money. 185709

I was unable to find the size Bearing buddy that I needed at other retailers.

Do you have a question about this Grease Cap?

  • What Size Bearing Buddy to Replace 2-7/16-Inch Grease Cap
  • The best way to measure hub bore to determine which Bearing Buddy size you need is with a digital caliper. If you do not own one you may be able to borrow or rent one from a local auto parts store. Your other option is to obtain the outer bearing number from your trailer. You may be able to obtain the bearing number without having to pull it from the spindle; try wiping it clean of grease to see if the bearing number can be read. The size you quoted, 2-7/16 inches, corresponds to...

  • Bearing Buddies for a 6,000 Pound Dexter Axle with 8 Lug Hub
  • Check the outer bearing and race numbers stamped into the metal of the bearing and race in the hub. Most 6,000 pound 8 lug wheels we carry use outer bearing # 14125A if it is an 8 on 6-1/2 bolt pattern. If it is an 8 on 8 bolt pattern, it may use # 506849 outer bearing. If you have the 14125A outer bearing, you can use Bearing Buddy Bearing Protectors, # BB2717SS, or # BB2717.

  • Replacing Zerk Fitting on # BB2441 Bearing Buddy
  • The zerk fitting is a standard size. The fitting is threaded, and is secured by a nut located on the inside of the bearing buddy. You should be able to obtain a replacement zerk fitting from your local auto parts store.

  • Bearing Buddies Recommendation for a Dexter P-11 6 hole axle 6K Axle
  • In order to determine which bearing buddies you need, you are going to need to remove the hubs of your trailer and get the number off of the outer bearings. Most 6K axles have outer bearing numbers of LM-67048, 15123, LM-67010 or 15245 which all will work with the Bearing Buddy Bearing Protectors # BB2441 that you referenced.

  • Which Size of Bearing Buddy Will Fit the Dexter Trailer Hub Assembly # 8-213-5UC1
  • The grease cap included in this hub kit # 8-213-5UC1 has an outer diameter of 2.44-inches. So the correct Bearing Buddy would be part # BB2441 or if you want the stainless steel version that will resist corrosion much better you would want the # BB2441SS instead.

  • Bearing Buddies for Dexter Axels with 6 Lugs on My Fifth Wheel Trailer
  • You will most likely need the Bearing Buddy Model 2441 for your trailer with Dexter axles. You should measure to be sure, before ordering. The outside diameter of the original drive in grease cap seating surface should be 2.44 inches. If your grease cap is too damaged to get an accurate measurement then you can measure the inside diameter of the cap seating surface on the hub which should also be 2.44 inches. If your grease cap measurement is different let me know and we will get the...

  • Installing Bearing Buddy Bra # BB23B
  • As a first step, make sure you are using the correct Bearing Buddy Bra for your application. The # BB23B you mentioned is sized to fit Bearing Buddies that fit hub bores ranging from 2.240 inches to 2.562 inches, or model #s BB2328, BB2328SS, BB2441, BB2441SS, BB2717, BB2717SS, BB2562, BB2562SS, BB2240 and BB2240SS. Applying a very very small bit of grease (I am talking tiny) to the outside of the Bearing Buddy will allow the bra to slide on easier. While sliding the bra into place,...

  • If you will remove the wheel on your trailer and pull your wheel bearings and get the outer wheel bearing part number that would help you with which Bearing Buddy to use.

  • How to Determine the Right Bearing Buddy Bearing Protector for 2-3/8 Inch Hub Bore
  • To choose the correct bearing protectors, if available, you will have to measure the hub opening using dial or digital calipers because the measurement has to be as exact as possible. Bearing protectors are measured to the thousandth of an inch (3 decimal places). None of the bearing protectors we carry are exactly 2-3/8 inches (2.375 inches) but # BB2328 and # BB2328SS are the closest at 2.328 inches. The next step up, # BB2441, at 2.441 inches would likely be too big if the measurement...

  • Do Trailer Hub Bearing Buddies Also Work with Inner Bearings
  • A Bearing Buddy allows you to pump grease into the center of the hub all the way back to the grease seal. A double lip seal should be used to prevent grease from blowing out the seal when added. You can pre-pack the bearings if you wanted to but that would negate the function of the Bearing Buddy. The outer bearing is mentioned because that is how the hub bore size is determined.

  • Determining Size of Bearing Protector Needed for 2001 Load Rite Trailer
  • The best way to determine the size of bearing buddy needed would be to take a highly accurate measurement of your hub bore using a digital caliper. I have edited a photo for you that shows this dimension. If you happened to know the reference number from your outer wheel bearings, the proper bearing protector could be determined. If you would care to reply with either the hub bore dimension or the outer bearing number, I would be happy to suggest a bearing protector for you.

  • How Do I Determine What Bearing Buddy Bearing Protectors I Need for My 2006 Pilgrim Cirrus Camper
  • In order to see if the Bearing Buddy Bearing Protectors, # BB2441, are the correct ones for your trailer, you will need to measure the inner diameter of your hub bore. This measurement needs to be very accurate so you will want to use a dial caliper. If the inner diameter of your hub bore is 2.441 inches, # BB2441 will work for you. If it is not, I am attaching a link to all of the Bearing Buddy Bearing Protectors that we have available. Take your measurement and match it to one...

This set of bearing protectors includes rubber covers.

  • 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...

  • Recommended Bearing Buddy Bearing Protectors for Montana Travel Trailer
  • To determine which Bearing Buddies you'll need, use a digital caliper to measure the inside diameter of the hub bore, not the outside diameter of the grease cap. Given the 2.443 inch dimension you provided, it's extremely likely that you'd need the model 2441 Bearing Buddy which measures 2.441 inches in diameter. They're available in chrome as part # BB2441 or stainless as part # BB2441SS. If your hub bores are threaded, use part # BB2441T-SS. I'd still recommend you measure for confirmatio...
