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.
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
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. Picture of the trailer being overhauled before new fenders were added.67986

This product is just great. I've used these on my other trailers and I swear by them. They stay in place under very rough conditions and do a fine job of keeping the bearings greased.80597

The Buddy Bearings arrived at my home before the weekend and I was able to install them on my trailer in time for my weekend on the lake. The bearings arrived much quicker than I had expected.21337
