SKF 26373 Heavy-Duty Pinion Grease Seal CRWA3 Style 2.625" Shaft

The SKF 26373 is a heavy-duty LDS (Lip Design Seal) grease and oil seal engineered for demanding pinion and truck axle applications. Sold under the SKF CR Seals brand, this CRWA3-style seal features a spring-loaded primary lip with an auxiliary dirt lip and an installation stop flange for consistent, repeatable seating depth every time.

A key design highlight is the SKF patented Bi-Directional Wave Seal geometry, which provides positive fluid control and hydrodynamic pumping action to actively return lubricant to the sump, reducing the risk of leakage even under demanding operating conditions. The seal compound is formulated to perform well with Extreme Pressure (EP) lubricants and resists oxidation and ozone degradation across a broad service temperature range of -40°F to 300°F.
