Bearing Buddy 1980 Chrome Plated Wheel Bearing Protector - 1.980 Inch Hub Bore

The Bearing Buddy 1980 is a chrome plated wheel bearing protector built for trailer hubs with a 1.980 inch (50.29 mm) inside bore. It mounts onto the outer end of a trailer hub and keeps water and dirt out of the wheel bearings while making it fast to check and top off grease level without removing the hub or dust cap. This model is designated 'without Bra,' meaning it is supplied as the chrome protector unit itself, without the added rubber protective bra cover.

Inside the hub, this bearing protector is designed for use with an outer bearing cone of L-44643, L-44649, or L-44640, paired with an outer bearing cup (race) of L44610. It is compatible with marine grease for lubrication. The housing is chrome plated steel for corrosion resistance in wet, road-spray, and marine trailering environments, and it is intended for boats, RVs, ATVs, and utility trailers using a hub built to the 1.980 inch bore spec.
