Detailed Description

SKF 18603 is a wheel seal designed for driveline and axle sealing service, with dimensions that matter for proper wheel-end fitment: 2.632-inch outside diameter, 1.875-inch shaft diameter, and 0.328-inch width. The nitrile sealing surface type supports dependable contact at the sealing interface, helping maintain lubricant inside the assembly while keeping road contaminants out.

  • Noise or service concerns caused by compromised sealing surfaces

Installation Notes and Tips

Verify shaft diameter, outside diameter, and width before installation to confirm correct wheel seal fitment.
