010-063-00 - Unitized Hub Seal

The 010-063-00 Unitized Hub Seal is a one-piece (unitized) grease seal designed to provide superior sealing performance for trailer hub assemblies. Unlike traditional two-piece seals, a unitized seal combines the sealing elements into a single assembly, improving durability, reducing installation errors, and offering enhanced protection against grease loss and contamination.

Commonly used on Larson Cable Trailers, this unitized seal is typically found on heavy-duty trailer axles, including 8,000 lb applications, where long-term bearing protection is critical.
