Detailed Product Description

The SKF 27438 wheel seal is designed to fit driveline and axle assemblies requiring a 2.750-inch shaft diameter and a 3.784-inch outside diameter. Its 0.762-inch width allows for a snug fit that prevents leakage of lubricants and ingress of dirt or moisture.

Installation Notes and Tips

When installing the SKF 27438 wheel seal, ensure the shaft and bore are clean and free of debris. Use appropriate tools to press the seal evenly into place without damaging the sealing lip. Verify the correct orientation of the seal, with the nitrile sealing surface facing the lubricant side. Proper installation will help maintain the integrity of the seal and extend the service life of your driveline components.
