PROTECTS YOUR BEARINGS FROM DUST & HIGHLY CORROSIVE SALT WATER
Trailer bearing protectors are spring-loaded metal caps that replace the dust caps on a trailer's hub. This is especially true of boat trailers that enter the water when the boat is launched. The protectors keep dirt and water out of the trailer bearings and keeps grease inside the hub, even when submerged. Trailer bearing protectors have a spring inside to keep constant pressure on the trailer bearings in any condition, wet or dry. This keeps contaminants out while keeping towing and bearing grease in, prolonging the life of the tow bearings and reducing the need to repack or replace them every year or two. Dry or dirty bearings wear down over time, keeping the hubs from rotating freely.
