Features & Benefits

Warranty: Standard : Limited Lifetime


The original product, now proven in 20 years of service. It replaces the dust cap in the wheel hub. The hub is filled with grease through a fitting on the Bearing Buddy. The patented spring loaded piston then holds a slight pressure inside the hub. When wheels are submerged, this higher inside pressure (together with the hub being full of grease) keeps out water. The automatic relief valve feature limits pressure inside the hub to protect the rear seals from rupture. Since the hub is full of grease, the bearings receive constant lubrication and the rear seals last they ride on a greased surface. Bearing Buddy allows quick lubricant level check and ends the need to repack bearings. Bearing Buddy is made of steel and each unit is inspected to assure tight, long term hub fit.
