Detailed Description

This axle spindle seal is engineered to retain grease and oil at the spindle while limiting the entry of dirt and other contaminants that can lead to leakage and wear. The reinforced outer case adds support during installation, while the ribbed inner diameter helps the seal maintain contact on the spindle surface. Vent holes allow lubricant circulation around the lip, which helps manage heat in service. This Timken 340835 seal cross-references BBB Industries 11050 for the same application.

Installation Notes and Tips

Inspect the spindle, housing bore, and sealing surface before installation. Clean away old grease, debris, and corrosion so the seal can seat evenly.
