Bearing Buddy 2328SS Stainless Steel Bearing Protector for 2.328 Inch Hubs, Boat and Utility Trailers

The Bearing Buddy 2328SS is a stainless steel wheel bearing protector designed to fit trailer hubs with a 2.328 inch inside diameter, including boat trailers, ATV trailers, utility trailers, and horse trailers. Instead of a plain dust cap, it functions as a pressurized bearing cover system: a spring-loaded piston maintains a safe 3 psi of pressure inside the hub, which keeps grease pushed against the seals and keeps water and road dirt out. The self-regulating pressure relief valve automatically releases excess grease during servicing or heat buildup, protecting the inner seal from damage caused by overpressurization while keeping the bearing properly lubricated.

Constructed from corrosion-resistant stainless steel, the 2328SS is built to hold up under saltwater exposure, making it a common choice for boat trailers as well as RVs, ATVs, and horse and utility trailers. It is manufactured in the USA and is quality inspected for a precise fit. Installation is straightforward: measure the hub to confirm proper fit, then tap the bearing protector into place using a wood block and hammer. If it does not fit securely, do not force it.
