Bearing Buddys premium quality stainless steel protectors are real easy to install and give perfect grip and cover with continuous enhanced lubrication to save you a peace of mind while on road or in water. Bearing Buddies for Boat Trailers Trailering, even a short distance, heats the hubs. When the wheels are submerged during launching, the hubs suddenly cool and the air inside the unprotected hubs contracts, forming a vacuum which draws in water through the rear seals. There is no such thing as a rotating seal that stays perfect. Water and grit thus drawn into the hubs relentlessly destroy bearings. When properly installed and maintained, these little marine Bearing Buddy guard wheel bearing system from failure and eliminates bearing repacking. Boat trailer wheels can be completely submerged. Utility Equipment, ATV, Horse, Camping, Snowmobile and other occasional used trailers These tow trailers, because they are not used regularly, are also subject to bearing corrosion and failure from condensation moisture from air sucked into hot hubs as they cool. Moisture stays in the hubs causing rust and pitting until they are reheated when the trailer is used again. On any vehicle, protecting your wheel bearings from dirt, dust, water, salt, sand and other contaminants is critical, so when it comes to using grease caps, you don't have much of a choice. That's their job. You either use them and your wheel bearings will remain useful, or you don't, and your wheel bearings wear out in a hurry. Buy your bearings a new buddy to play with, Click BUY NOW

• PROTECT YOUR INVESTMENT - Whether it’s a boat, camper, or utility trailer, our Bearing Buddy prevents wheel bearing failure. Keeps water and dirt out of hubs and bearings. Paired with the Bearing Buddy Bra, which keeps grease out of your wheel and adds protection
• EASY MONITORING - The blue visual grease indicator shows when your hub is properly filled with grease. When full, it extends out the retaining ring a ⅛”; when it’s flushed under the ring, it’s time to add more grease
• KEEPS GREASE IN & WATER OUT - Bearing Buddy has a spring-loaded piston that keeps a steady 3 psi of pressure inside your hub to hold grease in and block out water and dust. Bearing Buddy limits the pressure to 3 psi, preventing overfilling and overpressurization. Without this feature, the inner seal will be damaged
• QUICK & SIMPLE INSTALLATION - Measure the inside diameter of your trailer hub or the outside diameter of the dust cap with a caliper for a precise measurement and correct fit. Then, tap Bearing Buddy into place using a wood block and a hammer. No special tools or experience required
• BUILT TO LAST - Manufactured in stainless steel, the Bearing Buddy stands up to saltwater environments. These wheel bearing protectors are also proudly made in the USA and backed by a Lifetime Warranty, giving you long-term peace of mind
