Bearing Buddy installed diagram

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.

Fast shipping as always with etrailer. Measured inside diameter of hub with calibers and etrailer was the only one with that size. Fit perfect and easy install with a block of wood and hammer.




by:

Fits as they should. Easy to install. I have them on 4 trailers. Would not use anything else.




by:

The Bearing Buddys were exactly as described and shipping was fast.
If you are buying Bearing Buddy’s measure VERY carefully. I bought model2240 based on my measurement and they were too small by .08 inch. I then ordered the 2328 which were a perfect fit.




by:

The Buddy Bearing ordered fit great based on the information received from etrailer advisor. They were very helpful based upon measurements supplied to them. The Buddy Bearing has performed excellent.




by:

I was looking for a difficult core size, (2 & 5/16"), and "thanks etrailer" for helping me after I first ordered the wrong size. I got my correct Bearing Buddy set for my older boat trailer. I am excited to put them into action.

The BB2328 is the exact size. It was difficult to get them started, as the alignment required exactness, but I managed and I will not worry about them to fall out or easily be stolen. These BBs are a seamless fit. Thanks again etrailer...




by:

Anyone with any trailer experience has already heard of "bearing buddy" and if it wasn't a great product there wouldn't be so many copy cats. What impressed me the most was the fact they had them in the 2.3" size, and even more impressive is etrailer was the only place I could find them. To top it all off, I needed them in a hurry and etrailer got them here on time. They are great to use on any trailer, but I would never have a boat trailer without them, EVER.

Great product. Great distributor. Thanks etrailer!




by:

I received the wrong size buddy bearings. Asked for return info but never received.




by:

My buddies fit a little loose. I used a little lock-tight and some tension pins to keep them in place.




by:

Bearing Buddies are excellent for boat trailers. etrailer.com provides prompt delivery of what I need




by:

I will not be using this for 3-4 weeks because the trailer is at a different location....However the initial sale and shipment have been serviced with excellent speed and communication


Thank you very much




by:

Contacted etrailer.com by phone and spoke to John H. Extremely helpful and was able to steer me to the right size of bearing protectors that I needed. Will be shopping here again.

  • Bearing Buddies for a Boat Trailer with 2.308 Hub Bore
    Losing grease/dust caps or bearing protectors is all too common. It usually happens when caps are not driven in properly. The spinning of the wheel and the centrifugal force then causes the caps to wiggle free and fall out. Given that your hub bore measures 2.308 inches the best match would be a 2.328 model such as # BB2328. It will be a tight fit, which is what you want. To drive them in flush place a block of wood against the Bearing Buddy and tap the wood all around, not just in one...

  • Bearing Buddy Recommendation for Hub Bore Size 2-3/8 inches
    2-3/8 in decimal is 2.375 inches. The closest Bearing Buddy to that is the part # BB2328 which is for 2.328 inch hub bores.

  • Selecting a Bearing Buddy Bearing Protector for Utility Trailer with 2-1/3-Inch Hub Bore
    In order to select a Bearing Buddy Bearing Protector such as # BB2328 you will need to know the hub bore to the nearest thousandth of an inch (three decimal places), e.g. 2.328-inches. Bearing Buddies come in many sizes and the differences between them can be quite small. Also, some have threads to allow use in threaded hubs. The best way to proceed is to use a precision digital caliper to take your measurement. You can then use the link provided to select a Bearing Buddy kit that has...

  • Availability of Grease Cap for 2.3125 Inch Hub Bore Diameter
    The closest grease cap we have available to the 2-5/16 (2.3125) inch measurement you took on your hub bore is the Bearing Buddy Bearing Protectors # BB2328. These are designed to fit hub bores that have an inner diameter of 2.328 inches. This is awfully close to your measurement, but they still might be a bit too large to fit your hubs if your measurement is correct. I just recommend verifying your measurement one more time to make sure you are getting an accurate reading. I have attached...

  • Correct Bearing Buddy Bearing Protectors for 2-3/8" Hub
    The correct way to find the right Bearing Buddy Bearing Protectors is to measure the hub bore with a caliper to the nearest thousandth of an inch. That said, 2-3/8" or 2.375 would match up best with our part # BB2328 which is for a 2.328" hub bore.

  • 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...

    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 Find the Correct Replacement Idler Hub That Uses Bearing Buddy For 2.328 Inch Bore
    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. Therefore, the only option I have for you to confirm the correct replacement idler hub is to pull the hubs and measure the spindle using the...

  • Grease Cap Recommendation for Hub Bore of 2.3125
    Sounds like the part # F001926 would work as a standard grease cap as it is designed to fit hub bores of 2.333. However, this is a pretty short cap at only 1.281 inches. The other solution you have would be a Bearing Buddy like part # BB2328. This is designed to fit hub bores of 2.328. Bearing Buddies are similar to grease caps, except they have a zerk fitting on them that allow the spindle to be lubed easily.
