Description
Trailer Axle Seal – Oil Lube, 2.250″ ID x 3.376″ OD, Unitized, for 8K–9K Axles (Pre-1989)
This unitized oil seal is designed for use with 8,000 lb and 9,000 lb trailer axles manufactured before 1989. It features a 2.250-inch inner diameter and a 3.376-inch outer diameter, making it a precise fit for older-style hub and spindle configurations.
The unitized construction combines the sealing lip and metal casing into a single integrated piece, improving durability, sealing efficiency, and resistance to contamination. This design helps prevent oil leakage while keeping out dirt, dust, and water—extending the service life of the axle bearings and improving overall trailer performance.
Intended for oil-lubricated hubs, this seal is an essential component in maintaining proper lubrication and preventing gear oil loss in heavy-duty trailer applications such as livestock haulers, flatbeds, and industrial equipment trailers.
Constructed from high-quality materials to withstand high temperatures and rotational stress, this seal is a reliable replacement option for legacy axles requiring consistent and secure oil retention.
