Reliable Bearings Wheel Seal 1.987, Part Number SL-150-1, Trailer Hub Wheel Seal

The Reliable Bearings Wheel Seal 1.987 (part number SL-150-1) is a trailer hub wheel seal sized to the 1.987 nominal seal specification, a size commonly used across trailer hub and bearing assemblies. It is designed to seal the inner hub cavity, keeping grease inside the hub and contaminants such as water, dirt, and road debris out, which helps protect the wheel bearings from premature wear and corrosion. This seal is categorized under trailer hubs and bearings, making it a replacement component for trailer hub service and maintenance work where a 1.987-size wheel seal is called for.

At 1 pound, this is a standard single-unit wheel seal intended to be installed as part of routine trailer hub bearing maintenance or a full bearing repack service. Always confirm your hub's seal bore and shaft dimensions match the 1.987 sizing before ordering, since wheel seals are sized precisely to the hub they are installed in.
