Bearing Buddy Chrome Wheel Protector for Trailers Bearing Protectors, Seals & Bearings

Bearing Buddy Chrome Wheel Bearing Protectors replace the standard dust cap in a trailer hub. They help keep water and dirt out of the hub and bearings and make it easy to keep the hub filled with grease. They suit boat, utility, RV, ATV, snowmobile and horse trailers, and they help prevent wheel bearing failure.

Key Features:

• Keeps grease in and contaminants out: a spring-loaded piston holds the hub under light, constant pressure (about 3 psi). This helps keep water out, even when the wheels are submerged.
• Less repacking: you add grease through the protector's fitting, so you don't have to pull the hub apart to repack the bearings.
• Automatic pressure relief: if the hub is overfilled, excess grease can escape. This protects the inner seal from overpressure.
• Visual grease indicator: a colored ring shows at a glance whether the hub has enough lubricant.
• Durable construction: a chrome-plated barrel is paired with stainless steel internal components for corrosion resistance and long service life.
• Simple installation: measure your hub, choose the matching protector, and tap it into place with a block of wood and a hammer.

Each model is made for a specific hub inside diameter. Measure your hub's inside diameter, or the dust cap shoulder that fits into the hub, before you choose a model. Bearing Buddy is a well-known name in trailer bearing protection and offers these chrome protectors in a range of sizes for common trailer hubs.
