Buddy Bearings

If you tow a trailer you need Genuine Bearing Buddy®.

When backed into water for launching, boat trailer wheel hubs, heated by travel are suddenly cooled. Air inside contracts. A vacuum is created. Water and dirt are sucked into the hubs through the inner seals and corrosion sets in immediately. Bearing failure can be expected within two seasons in fresh water - one season in salt water.

When properly installed and maintained, Bearing Buddy® prevents wheel bearing failure and eliminates bearing repacking. Boat trailer wheels can be completely submerged-safely.

Bearing Buddy® also prevents bearing failure on motorcycles, utility, snowmobile, camping and other trailers by eliminating moisture build-up in hubs and providing proper lubrication.Bearing Buddy® will last the life of your trailer and then some. The outer barrel and components are made of stainless steel.

Eliminates bearing repacking.

Keeps water and dirt out of hubs and bearings.

Grease level easily checked.

Easy to install.

Buddy Bearings Operation

Replace your existing grease cap with a Buddy Bearing 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.
