Bearing Buddy 2.401" Chrome Trailer Wheel Bearing Protector, 2-Pack (43401)
The Bearing Buddy is the original pressurized wheel bearing protector, designed to keep trailer bearings running longer by maintaining positive grease pressure inside the hub. This chrome-plated model fits hubs with a 2.401" bore diameter and actively blocks water, dirt, and road grime from reaching your bearings — even after repeated submersion during boat launches. A 2-pack covers both wheels on a single axle.

- Positive-pressure grease system prevents water and contaminant intrusion

Parts Desk Insights
Best Use Case: The 2.401" bore is a common size on mid-range trailer axles. This is a straightforward freshwater and general-use fit — if your trailer sees regular saltwater exposure, step up to the stainless steel version for better long-term corrosion resistance. Note that the 43402 (2.402") is just 0.001" larger and may also be worth comparing for your specific hub. Always measure your hub bore before ordering. For trailers with drum brakes, pair with the Bearing Buddy Spindo Seal to complete the hub seal. To keep excess grease off your tires and wheels, the Bearing Buddy With Bra version includes a vinyl cover for a cleaner installation.
