Bearing Buddy 43712 – 2.717" Chrome Bearing Protector with Bra, 2-Pack
The Bearing Buddy 43712 is a chrome-plated bearing protector designed to keep water, dirt, and road contaminants out of trailer wheel hub bearings while maintaining proper grease pressure. The spring-loaded piston inside the Bearing Buddy maintains positive grease pressure in the hub, preventing water intrusion during boat trailer submersion. An automatic pressure relief feature allows excess grease to escape if the hub is overfilled, protecting seals from over-pressurization. Includes the Bearing Buddy Bra — a vinyl cover that fits over the unit to contain any excess grease and keep it off tires and wheels. Sold as a 2-pack (one pair).

Parts Desk Insights
The most important spec to confirm before ordering is the hub bore diameter — 2.717" is a less common size, so measure the existing hub bore or check your axle specification before purchasing. Bearing Buddy units are available in a range of bore sizes; if 2.717" doesn’t match, see the 2.560" Chrome, 2.562" Chrome, 2.441" Chrome, or 2.402" Chrome options. For stainless steel versions, see the 2.444" Stainless and 2.448" Stainless. For trailers with brakes, see the Bearing Buddy Spindo Seal.
