SKF 16993 Differential Pinion Seal Grease Seal

The SKF 16993 is a differential pinion seal (grease seal) engineered to keep lubricants in and contaminants out of the differential pinion assembly. Designed for cars and light trucks, this radial shaft seal delivers reliable sealing performance under the demanding conditions of drivetrain operation.

Key Features:

• Advanced elastomer construction — specially formulated sealing lip materials provide high durability in corrosive and high-temperature environments
• Precision fit — manufactured to exacting dimensional tolerances for a reliable, leak-free installation
• Contaminant exclusion — effective barrier against dirt, moisture, and road debris that can degrade differential fluid and bearings
• Lubricant retention — maintains proper fluid levels within the differential to protect gears and bearings from premature wear
• Metal-reinforced case — provides structural integrity and secure housing bore retention
• SKF Bore Tite coating — helps seal the outer diameter against housing bore leakage

SKF has been a leader in seal design and development for over a century, and the 16993 reflects that heritage with premium materials and consistent quality. This seal is a direct-fit replacement for the differential pinion position, restoring OEM-level sealing performance.
