SKF 47691 Wheel Seal - Rear or Rear Inner

SKF Scotseal PlusXL Wheel Seal

SKF 47691 is a premium wheel seal built for demanding driveline and axle service. It uses HNBR material for heat resistance and synthetic lubricant compatibility, making it a strong choice for frequent braking and harsh operating conditions.

Key Features

• SKF Scotseal PlusXL design for extended service life
• HNBR sealing material rated for heat resistance up to 300 degrees F
• Compatible with today’s synthetic lubrication fluids
• Hand-installable design with a stable footprint on the shaft
• Built to help keep lubricants in and contaminants out

Detailed Description

The SKF 47691 wheel seal is engineered for axle and hub sealing where temperature, lubricant compatibility, and contamination control matter. Its HNBR construction is suited to frequent braking cycles and severe-duty use, while the seal profile is designed to maintain stability during installation and operation. SKF has long experience in sealing systems, and this Scotseal PlusXL design reflects that focus on durability in real-world service.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Gear oil or lubricant leakage at the wheel end
• Contamination entering the hub or axle area
• Heat-related seal wear from repeated braking
• Poor seal performance with synthetic lubricants
• Premature seal failure in harsh road conditions

Installation Notes and Tips

Inspect the shaft, hub, and bore for wear, scoring, or contamination before installation. Clean all sealing surfaces thoroughly and verify the seal seats evenly to avoid distortion. Use the correct service procedure for the axle or hub assembly to protect the sealing lip and maintain proper alignment.
