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.

Video Transcript for Bearing Buddy Grease Caps BB2441 Review

Today, we are going to be taking a look at the bearing buddy bearing protector, model 2441. These are going to replace the grease caps on the axle hub. The bearing buddy is going to prevent wheel bearing failure. What the bearing buddy does is it keeps water and dirt out of the hubs and bearings. It allows for boat trailer wheels to be completely submerged, and it's going to stop corrosion and pitting on the bearings. You're going to get two bearing buddies. Each was one is going to have a rubber cap that gets installed over the end of the bearing buddy.

Once you remove that, it's going to expose the grease fitting. That is going to be easily accessible. It makes adding grease to the bearings quick and simple. You don't ever have to worry about having to repack your bearings. This units a really great addition, keeps thing clean.

It's just very easy to use and maintain those components that are sometimes quite a mess to maintain. The unit's also designed to maintain slight controlled pressure, about 3 PSI with a spring loaded piston, which is going to prevent water from entering the hub. The unit also prevents over filling and rear shield damage, which is great. It's going to feature automatic pressure relief feature. If grease appears around the edge of the piston when filling with grease, this is a result of the automatic pressure relief feature functioning. The piston rides on a rubber O-ring, and once that piston strokes out beyond the O-ring, grease will escape in this area here.

That way the hub can't be over filled, and it can't be pressurized. The unit's constructed of stainless steel internal parts, and triple chrome plated steel barrel. It's going to ensure longer lasting fits, when compared to plastic or aluminum products. Again, it's going to include the rubbed covers to keep any grease of of you wheels. The bearing buddy's going to contain a grease fitting. It's going to have the spring.

It's going to have an O-ring It's going to have the piston, and eternally it's going to contain an outer bearing. The unit is assembled and ready for installation right out of the box. Installation is pretty simple. Just hold it against the hub, so this would go up against the hub. Hold it against the hub, and drive it into place with a small block of wood or a soft mallet. These are designed to fit 2.441 inch hub bores. Those are going to be commonly found on forty-four hundred, fifty-two hundred, six thousand pound, and seven thousand pound axles. Bearing buddies are made, right here, in the USA, and they are going to be covered with a lifetime warranty. That's going to do it for today's look at the bearing buddy bearing protectors, model 2441.

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

This product is as good as their rep have used them before on a boat trailer never had a bearing go out as long as I used the buddy bearings they are great! Service was just as good. These bearings were installed on a heavy duty low boy trailer. No pictures trailer is in South Texas about 300 miles from my location. Hauling oil field equipment.

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. I actually found this by coming across another question that a shopper had asked that referred to the same unit I was looking for. Thanks for having a question and answer forum and thanks for stocking the hard to find items! 214817

I put 4 of these on my 26' fifth wheel. The installation was very easy and exactly as described. I tapped them gently with a hammer to get them started and then used a block of wood and hammer to seat them fully for a nice tight fit. 255676
