Reliable Bearings Wheel Seal SL-225-1, 3.371 Inch, Trailer Hub Bearing Seal

The Reliable Bearings Wheel Seal SL-225-1 is a 3.371 inch trailer hub seal designed for use in trailer hub and bearing assemblies. It is part of the Trailer Hubs & Bearings product line and is built to keep the hub cavity sealed against water, dirt, and road debris while retaining the lubricant that protects the wheel bearings inside. A properly fitted wheel seal is one of the most important components in a trailer hub assembly: it prevents grease from leaking out and contaminants from working their way in, both of which are common causes of premature bearing failure on boat trailers, utility trailers, and other towed equipment. The SL-225-1 seal weighs 1 pound as packaged. Because the exact bore, shaft, and hub dimensions of a wheel seal must match the hub it is installed in, confirm that the 3.371 inch size matches your hub or bearing specification before ordering. This seal is sold as a standalone replacement part for hub servicing and bearing repacking jobs.
