Bearing Buddy 42411 2.047" Wheel Bearing Protector with Bra

The Bearing Buddy 42411 is a chrome-plated wheel bearing protector designed for trailer hubs with a 2.047" inside diameter. It replaces the standard dust cap and works by maintaining constant grease pressure inside the hub, protecting wheel bearings from water intrusion, dirt, and road debris.

Key Features:

• Precise Fit: Designed exclusively for trailer hubs with a 2.047" inside diameter — measure your hub with calipers before ordering
• Spring-Loaded Pressure System: Maintains approximately 3 PSI of internal pressure to prevent water from penetrating the hub during submersion or wet conditions
• Automatic Pressure Relief: Self-regulating design releases excess grease to protect seals and bearings from overfilling damage
• Includes Bra: Comes with the Bearing Buddy 19B vinyl bra cover, which fits over the protector to contain excess grease and keep it off tires and wheels
• Stainless Steel Internal Components: Corrosion-resistant internal parts with a triple chrome-plated steel barrel for long-lasting durability
• Easy Installation: Presses directly into the hub opening; fill with grease via standard grease gun — no special tools required
• Made in the USA

The Bearing Buddy is ideal for boat trailers, utility trailers, ATV trailers, horse trailers, RV trailers, and snowmobile trailers. By keeping bearings properly lubricated and sealed, it helps eliminate the need for periodic bearing repacking and can significantly extend bearing service life.
