SKF 9859 Steering Gear Worm Shaft Seal

The SKF 9859 steering gear worm shaft seal is built for steering gear sealing applications where shaft diameter, outside diameter, and sealing surface material must match precisely. With a 1.000-inch shaft diameter, 1.503-inch outside diameter, and 0.188-inch width, this SKF seal is made for accurate fitment in steering gear service work.

Key Features

  • Steering gear worm shaft seal for sealing system repair
  • 1.000-inch shaft diameter for proper shaft fit
  • 1.503-inch outside diameter for housing sealing
  • 0.188-inch width for compact installation dimensions
  • Nitrile sealing surface type for fluid-resistant sealing performance
  • SKF part number 9859 for catalog and cross-reference lookup

Detailed Description

SKF has a long history in seal engineering, and the 9859 steering gear worm shaft seal reflects that focus on precise design and material selection. The nitrile sealing surface is selected for steering gear environments where lubricant retention and contamination control are critical. For service on steering gear assemblies in applications such as Ford and Chevrolet vehicles, this seal supports restoration of the worm shaft sealing interface when the original seal has worn, hardened, or begun leaking. The SKF 9859 is also referenced in aftermarket catalogs under part number 9859 for easier identification during steering gear repair.

This part cross-references Monroe Shocks & Struts 172788 for the same application.

What It Helps Fix

  • Steering gear oil seepage at the worm shaft
  • Loss of lubricant from the steering gear housing
  • Contamination entering the steering gear assembly
  • Steering play or rough operation caused by seal wear and fluid loss
  • Service issues during steering gear rebuilds on Ford and Chevrolet applications

Installation Notes and Tips

Confirm shaft diameter, outside diameter, and seal width before installation. Inspect the worm shaft and sealing bore for scoring, corrosion, or wear that could affect sealing performance. Clean the housing thoroughly and install the seal squarely to avoid distortion of the nitrile sealing surface. Verify steering gear condition and fluid level after service.

Quality Assurance

SKF designs and manufactures seals to specific application requirements using premium materials and controlled production standards. The brand’s seal engineering heritage dates back to the first integrated shaft seal, and SKF products are built for long service life and dependable sealing in automotive steering systems.
