Bearing Buddy 42202 Chrome-Plated Bearing Protector for 1.980 Inch Hub Bore, Fits L-44649/L-44643/L-44640 Bearings

The Bearing Buddy 42202 is a chrome-plated bearing protector designed to keep water, dirt, and grit out of the wheel bearings on boat trailers, utility trailers, and campers. It installs into a trailer hub with a 1.980 inches (50.29 mm) inside diameter, where it seals against the outer bearing cone and race to protect the bearing pack from moisture intrusion. A spring-loaded piston inside the unit maintains a steady 3 psi of pressure, which holds grease in and keeps water and dust out while preventing the hub from being overfilled or overpressurized, a condition that can otherwise damage the inner seal.

A blue visual grease indicator on the face of the unit shows lubrication level at a glance: when the hub is properly filled with grease, the indicator extends about 1/8 inch out from the retaining ring; when it sits flush or recessed under the ring, it is time to add grease. The body is manufactured from carbon steel with a chrome-plated finish for corrosion resistance in freshwater environments, and the internal components are stainless steel. Installation is done by measuring the hub bore or dust cap opening with a caliper to confirm fit, then tapping the unit into place with a wood block and hammer; no special tools are required. This unit is designed to work with outer bearing cone part numbers L-44643, L-44649, and L-44640, and outer bearing cup (race) part number L-44610. It is sold as the bearing protector only, without the rubber protective bra/cover accessory. Made in the USA and backed by a lifetime warranty.
