Bearing Buddy 2.328" Chrome Trailer Wheel Bearing Protector, 2-Pack (43102)
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 2.328" 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.
Features
- 2.328" bore diameter — fits hubs requiring the 43102 specification
- Chrome-plated steel barrel with stainless steel internal components
- Positive-pressure grease system prevents water and contaminant intrusion
- Eliminates the need for routine bearing repacking
- Easy press-in installation into existing hub bore
- Sold as a 2-pack — covers both wheels on one axle
- Compatible with optional Bearing Buddy Bra vinyl cover accessory
Compatible Applications
- Boat trailers with 2.328" hub bore diameter

Parts Desk Insights
Best Use Case: The 2.328" bore is a common size on smaller to mid-range boat and utility trailer axles, and this chrome model is the right choice for freshwater and general trailering use. If you want the Bra vinyl cover included for a cleaner installation, the 43105 chrome With Bra (2.328") is the bundle version at the same bore. For saltwater environments, step up to the stainless steel model — the 43104 stainless (2.328") or 43108 stainless (2.328") are the closest stainless options. Always measure your hub bore before ordering. For trailers with drum brakes, pair with the Bearing Buddy Spindo Seal to complete the hub seal.
