Detailed Description

SKF 18873 is a wheel seal designed for axle and hub sealing service where controlled lubricant retention is critical. The polyacrylate sealing surface is selected for the demands of the application, and the seal dimensions support proper fitment in the specified hub and shaft setup. SKF has a long history in seal engineering, including early integrated shaft seal development, and its products are manufactured to strict quality standards. This part number, 18873, is used across multiple older light truck and utility applications, including Chevrolet LUV, Mazda B2000, Mazda B2200, Mazda B2600, Isuzu Pickup, Isuzu Trooper, and Ford Courier.

What It Is Used For

• Stopping gear oil or grease from escaping the hub assembly.
• Reducing contamination from road debris, water, and dust.
• Addressing seal wear that can lead to leaks around the axle end.
• Restoring sealing performance during hub or axle service.
• Supporting proper operation in rear and rear outer seal locations.

Installation Notes and Tips

Verify shaft diameter, outside diameter, and width before installation. Match the application notes carefully, especially on Mazda B2000, Mazda B2200, Mazda B2600, Isuzu Trooper, and Ford Courier listings that include chassis breakpoints or production cutoffs. Clean the sealing bore and shaft surface thoroughly before installing SKF 18873 to help ensure a proper seal.
