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.

Great for marine applications; the stainless steel construction provides the best in corrosion resistance. The design makes Bearing Buddy an easy way to protect your bearings by keeping water out and ensuring enough grease is in the hub.


I have this boat trailer with drum brakes that are integral with the hub.. Water kept creeping in the bearings every time it was submerged. This resulted in great time and money spent maintaining them, with four wheels to service. I finally figured out that the wheels are usually much warmer than the water and this produces a vacuum inside the sprocket as they suddenly cool, thus sucking up water like a thirsty camel. I discovered these “bearing buddies” at tha are spring-loaded to pressurize the sprocket chambers, and this eliminates the problem. This website is my first choice tor trailer parts, and their customer service is tops.


Trusted product name and quality, offered at a decent price.


Fast ship high quality bearing buddy’s


The bearing protectors arrived and everything looks great, thanks for the excellent service. I have not installed them as of yet, have to clean and repack the bearings and just have not gotten to it yet. I did check them for fit and it is A ok.

No problems, everything has been working as well as possible. J. Scott


I purchased 15" fenders, buddy bearings & LED Lights from etrailer & they were all packed in one box & nothing was scratched or damaged! I obtain everything for my many trailers from etrailer & wouldn't waste any extra time researching other sights. These guys are the "BEST!" Don't waste your time, either. Go with etrailer!!


Etrailer is Simply the Best parts vendor contractor trailers wheels rims brakes unit wiring Katherine B took care of my order beautifully and so did other people I can't believe the response the respect the follow-up to make sure my parts were correct it is absolutely the best company to deal with in the United States as far as I'm concerned I've never had a company service me as a customer with love and respect like e trailer com has and Kathy Kathy Ed E trailer com she is outrageous stays on her business and so nice and respectful thank you Kathy


I think everyone should invest in getting bearing buddies for their trailer especially for marine and or boating purposes. I’m pleased with the product I ordered and received from etrailer. I have an odd ball hub size to begin with so I’m glad they had the bearing buddy size that I needed for my boat trailer. I haven’t installed these yet but when I do I’ll leave a further review and comment on the bearing buddy’s performance . But over all I’m happy with the product.


Great just great! Thanks to all. See pi ctures


I am very pleased. I received my order fast. I like the large selection of sizes. Especially since the ones I needed are and odd size that is hard to find. The price was good and they are good quality. Thank You



Doing great having no problems at all. Very pleased


Spare bearings and bearing buddy for my boat trailer so I would not be waiting on the side of the road for parts. Great prices and quick delivery.


You ladies are great! Your company is great Thank you


I have shopped at etrailer before and was happy with their service and products. The latest products and service was as expected.

That is why I continue to shop at etrailer - reasonable prices, good products,and service.


These are a necessary addition to your trailer. If you don't have them, get them. No other way to know that you have enough grease. I have used several times recently. All transactions were completed professionally. Thanks.


These bearing buddies are high quality and with non-corrosion resistant stainless steel. Well worth the price getting the peace of mind that water is not getting into my boat trailer bearings.


Received my order in just a couple of days and it was exactly what I needed. They went on with just a few taps from a rubber mallet and fit perfect. Now I can make sure to keep my bearings protected on the boat trailer. Thanks for the great service.


I ordered the bearing buddies on a Friday and received on Monday in Alaska. Very pleased usually all I hear is we don’t ship to Alaska thanks


Quality product and excellent service! Delivery met and on most occasions exceeded expectations. Have since purchased more product with same results! Highly recommend Etrailer Corp!


I ordered this as a spare part for a trip. I had the products shipped to my location and everything worked out GREAT

  • Bearing Buddy Fit for Ranger Trail Boat Trailer
    From your photos, it looks like you've got a 2-5/16 inch OD on those caps, is that correct? If your outer wheel bearing is # LM67048 (or if your outer bearing has a 1-1/4 inch inside diameter) the # BB2328SS would be the proper Bearing Buddy for you.

  • Bearing Buddy Recommendation for a Shoreline Boat Trailer to Replace 2-5/16 Cap
    The closest grease caps we have to what you would need would be the Bearing Buddies part # BB2328SS that fit a 2.328 hub bore which is very close to the cap dimensions you said you have. You might remeasure your caps with a digital or dial caliper to see if they are right at 2.328. The Bearing Buddies have a grease fitting on them so that would make greasing your hubs easy.

  • How To Determine what Bearing Buddy a Trailer Hub Would Need
    To pick out the correct Bearing Buddy you'd need to take off one of your trailer hub dust covers and measure the bore of the hub where the cap was and let me know what you have. If you measure 2.32 inches the part # BB2328SS would work.

  • 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...

    I do have options for you but I cannot confirm fit of a replacement idler hub based solely on the Bearing Buddy Bearing Protectors part # BB2328SS. These Bearing Buddy Bearing Protectors which have a 2.328" hub bore are common for 4,400 lb, 5,200 lb and 6,000 lb axles but the 5 bolt pattern you said you had is not common for these axle capacities.

  • How to Choose Bearing Buddies For Ranger Boat Trailer
    While it is really easy to determine which Bearing Buddies are the correct fit for your Ranger boat trailer, we have no way to confirm a fit on any specific make or model. For you to confirm the right Bearing Buddies I'd need to know either the outer bearing number, or you'd need to measure the hub bores on your trailer's hubs using a digital caliper like # PTW80157, then match the hub bore diameter to the correct Bearing Buddies. For example, outer bearings L44643, L44649, and L44640,...
