Wesbar BPC1980604 Trailer Wheel Bearing Protector with Dust Cover 1.980" Pair

The Wesbar BPC1980604 is a pair of 1.980-inch trailer wheel bearing protectors with dust covers, designed to deliver long-lasting protection for trailer wheel hubs against the damaging effects of water, dirt, and corrosion. Built from non-corrosive aluminum with a chrome finish, these bearing protectors are ideal for boat trailers, utility trailers, and any application where hubs are routinely exposed to water submersion or harsh environments.

Installed in place of a standard wheel hub dust cap, the bearing protector uses a spring-loaded piston that is charged with grease through a zerk fitting. The pressurized grease creates a positive internal pressure barrier, actively preventing water, condensation, and dirt from entering the hub and reaching the bearings. The system automatically maintains the correct internal pressure at all times, eliminating the risk of over-pressurization that could damage wheel seals.

Key Features:

• 1.980-inch inner hub diameter — fits hubs using L44610 bearing
• Spring-loaded piston design maintains constant positive internal hub pressure
• Grease added through a zerk fitting on the piston face
• Included dust cover bra captures any excess grease expelled during pressure relief, keeping wheels clean
• Non-corrosive chrome-finished aluminum construction resists rust and corrosion
• Sold as a pair (2 protectors + 2 covers)
• Compatible outer bearing cones: L44643, L44649, L44640
• Proudly Made in the USA
