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.

very helpful, fast shipper, pleasure to business with
The bearing buddy works great for an axle that has a very difficult grease cap to find. Just make sure your cotter key is close as possible to the castle nut so that it doesn't rub the bearing buddy.
Just what I needed for my hay trailer. These bearing buddy’s keep mud and water out of the wheel bearings on my hay trailer I use to haul round bales to the cattle in the winter.
They fit snuggly and give the the ability to keep the bearings greased via the zerk fitting on the bearing buddy.
THE BEARING BUDDIES ARE STILL IN PLACE.
NOT SURE WHEN I LOST THE PLASTIC/NYLON DUST COVERS
I HAVE PLENTY OF PEOPLE BORROWING MY CAR TRAILER IN BETWEEN
I recently purchased a trailer equipped with axles with discontinued hubs, however my hubs were in excellent condition. It was missing a dust cover from one of the hubs which was rare oddball size. etrailer had bearing buddies which were a perfect fit.
Great product. Worked great till I lost one. Then the second one was stolen with a different sized one on the other side of the trailer. Wish there was some way of locking them to the hub.
My bearing buddys shipped imediately and arrived in 3 days. They installed perfectly and i look foward to many years if convenient bearing srrvice. Etrailer has privided great setvuce every time I have ordered parts
Fits my non-standard sized trailer hub(2.221") perfectly.
