Bearing Buddy wheel bearing protector Model 1781 Chrome with 17B Bra — spring-loaded piston, seals hubs

This compact, durable hub cover is designed to preserve trailer, boat, and utility vehicle wheel bearings by maintaining correct internal pressure and keeping contaminants out. The 1781 features a spring-loaded piston to hold about 3 psi of grease pressure, a chrome finish over corrosion-resistant stainless steel for freshwater resilience, and ships with the 17B Bearing Buddy Bra to prevent grease from splattering onto wheels and rims.

How does the Model 1781 protect bearings during towing or storage?

The Bearing Buddy 1781 creates a controlled pressure environment inside the hub so grease stays where it belongs and dirt and water are kept out. By releasing only excess grease, the unit helps prevent seal blowout and reduces the chance of contamination entering the bearing cavity.

• Spring-loaded piston maintains safe internal pressure around 3 psi
• Chrome-plated stainless steel resists corrosion for freshwater use
• Includes 17B Bra to keep exterior wheel surfaces clean from grease
• Designed to fit common spindle/hub sizes when properly measured

What makes installation straightforward for DIYers?

Installing the 1781 is a simple mechanical process requiring basic tools and a little care with measurements. Tap the Bearing Buddy into the hub using a wooden block and hammer; no special tools or professional skills are necessary, though correct fit is essential.

• Measure hub bore to confirm compatibility before installation
• Use a wood block and hammer to seat the protector evenly
• If it doesn’t sit securely, stop and contact Bearing Buddy for support
• Can be installed during routine bearing repacking or as an upgrade

How does the 17B Bra add value to the bearing protector?

The included 17B Bra is a removable fabric cover that shields the wheel and rim from grease during operation, keeping your wheels cleaner and reducing the need for frequent cleanup. It also offers a minor cosmetic protection layer while the Bearing Buddy handles pressure regulation inside the hub.

• Covers the outside of the Bearing Buddy to prevent grease splatter
• Easy to slip on and remove for maintenance or inspections
• Reduces rim staining and simplifies post-trip cleaning

Who is this product for? The Bearing Buddy Model 1781 with 17B Bra is intended for owners of boats, RVs, ATVs, utility trailers, and horse trailers who want to extend bearing life and reduce contamination risk. It’s especially useful for users who trailer in wet conditions or store equipment near water, and for DIYers who perform their own wheel maintenance and want a long-lasting, low-maintenance protector made in the USA.
