BB2441SS-2.44” Stainless Steel Bearing Buddy Caps
This great design from Bearing Buddy provides an easy way to protect your trailer bearings by keeping water out and grease in. The Bearing Buddies are made out of stainless steel and provide maximum corrosion resistance for marine applications. All Bearing Buddies are made in the USA and has a Lifetime Warranty.
The 2.44” Bearing Buddy fits a hub bore of 2.44” and works with hubs that use outer bearing number of L15123. This bearing buddy is typically found on 4,400-6,000 axles using 6 lug trailer hubs.
- Made out of stainless steel to provide longer life for marine applications
- Can be used in place of the standard grease hub cap
- Add grease to your bearings and hub quickly from the grease fitting in the cap
- Prevents trailer bearing failure by maintaining a controlled pressure and preventing water from entering your trailer hub.
How Bearing Buddies Work
The axle hub is filled with grease until the grease forces the Bearing Buddy® piston outward about 1/8 inch. Because the piston is spring loaded, the piston exerts a slight (3 psi) pressure against the grease, which maintains a slight pressure between the inside of the hub and the outside environment. When the hub is submerged, water cannot enter the hub because of this pressure. An automatic pressure relief feature prevents over-filling and over pressurization.

Grease can be added to the hub through an easily accessible grease fitting located in the center of the piston. Lubricant level (and pressure) can be checked quickly by pressing on the edge of the moveable piston. If you can rock or move the piston, the hub is properly filled. Bearing Buddy® will last the life of your trailer. The outer barrel is made of steel and is triple chrome plated. Internal Bearing Buddy® parts are made of stainless steel. Bearing Buddy® is also available with a stainless steel barrel for maximum corrosion protection. (Source: BearingBuddy.com)
Installation and Removal of Stainless Steel Bearing Buddies
Remove hubs and check the bearings before installing Bearing Buddy®. Replace bearings if they are damaged, rusted, or pitted. Clean old grease and contaminants out of the hubs. Check the condition of the inner seals. Be sure they are new, top quality, and running on a smooth spindle sealing surface. IMPORTANT: As you reassemble the components, fill the hubs completely with a high quality, multipurpose, no.2 grade lubricant (e.g., the type used for automotive suspensions). Don't use heavy, fibrous greases; don't mix grease types.
BEARING BUDDY® INSTALLATION
Hold the Bearing Buddy® against the hub with a small block of wood, and drive it into place with a hammer. If Bearing Buddy® cannot be driven into the hub, or will not fit tightly into the hub, don't force it. Your hubs may be slightly oversized or undersized. If this occurs, or if the Bearing Buddy® is obviously too large or too small; contact your dealer. If you install Model 1980T (threaded), apply Permatex or some other grease proof gasket cement to the Bearing Buddy® threads, and then screw Bearing Buddy® into the hub, hand tight.
HOW TO REMOVE A BEARING BUDDY®
Bearing Buddy® is held in the hub by an interference fit. To remove Bearing Buddy®, lay a block of wood against the side of it and strike the wood with a hammer. Place the wood on the opposite side and hit again. Continue this procedure until you ''walk'' the Bearing Buddy® out of the hub. Don't disassemble the Bearing Buddy® to attempt to remove it.
