Provide your trailer wheel bearings with premium protection - replace your existing grease caps with Bearing Buddies. They install in seconds and provide an easy, safe way to monitor and control the level of grease in your axle hub.
Features:
Specs:
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.

Provide your trailer wheel bearings with premium protection - replace your existing grease caps with Bearing Buddies. They install in seconds and provide an easy, safe way to monitor and control the level of grease in your axle hub.Myself, I have been looking for nearly 3 years for the correct size, 2.047 and it was my friend that located your site. Both went on very snug. In the past I would purchase smaller ones and twist the inner surface and shove them on with little effort and then fly off during my travels. These Bearing Buddys went on Solid ! Harbor Freight wasn't any help at all. 160302
Bearing Buddy is a good product. I had to use a block of wood and a small sledge hammer to put them on. They would not go on with a rubber mallet. I measured 2.045" and the closest one from Bearing Buddy was 2.047"They are on and will not come off.... The trailer is a kit that I bought at depot in 1997... I would recommend this product 98794

Works great 850845
I am very pleased with the bearing buddy. I had lost the bearing cap and couldn't find a replacement at any auto shop. However, the BB2047 fit perfectly and keeps my bearings lubricated continuously. Replacing the cap did force me to repack the bearing, but that was probably a good thing as water had gotten in there. I feel the bearing buddy will protect my bearings probably for the life of the trailer; and since the grease is under positive pressure, water won't get in there. 818573
Wouldn't run a trailer without them. 811846
prompt delivery, perfect fit. 811442
I installed the Bearing Buddys and ran them for 100 miles or so before going on a 500 mile trip. On the first 50 miles on the highway one of the Bearing Buddys flew off and I lost it. The hub was no warmer than the other side and I was driving under 65mph in 60 degree heat. I also have new tires and bearings. The Bearing Buddy’s were very snug so I don’t know why they came off. I have used Bearing Buddys in the past with no problems, but now I feel like I need to carry a spare pair or at least one spare just in case. 809852

I think every trailer should have buddy bearings. My boat trailer is 26 years old. The trailer bearings are original and still working. I do make sure to lube them 2-3 Times a season. I probably launch about 12 times a year and put about 2000 miles on the trailer in a year. 733907

Great service and shopping! Thanks 718828
When you buy a trailer from Harbor Freight, then buy the bearing extenders, you'll most likely find that the only ones they sell (1.98) are too small. Measure your cap for the bearings and you'll probably have (2.47) which will fit perfectly. Go to etrailer website for the correct size and super fast delivery. Thanks etrailer Larry C. 717995
Perfect fit on Harbor Freight trailer. 714958
Customer service is excellent. Shipping is quick and reliable , always on time. Your follow up is welcome. Quality of product I thought would be somewhat better. One of the 2 worked but the other had to be reworked cause it didn't fit the opening of the trailer hub. I was able to make it work by grinding it down a little and some persuasion. Thanks 699065
