Overview of FAG SS2420 Differential Pinion Seal

The FAG SS2420 differential pinion seal is engineered to provide reliable sealing performance for driveline and axle applications. Designed with a metal casing, spring, and auxiliary lip, this seal ensures effective protection against leaks and contamination in various vehicle differentials.

  • Seal Type: Metal casing with spring and auxiliary lip for enhanced sealing
  • Sealing Material: Durable nitrile compound for resistance to oil and wear
  • Bore Diameter: 2.374 inches (60.3 mm) ensuring precise fit
  • Seal Outside Diameter: 2.378 inches (60.401 mm) for secure installation
  • Seal Width: 1.375 inches (7.95 mm) for optimal sealing surface

Technical Details and Specifications

The FAG SS2420 differential pinion seal features a nitrile sealing material known for its resistance to petroleum-based fluids and temperature variations common in automotive differentials. The metal outer casing combined with a spring and auxiliary lip design provides a tight seal around the pinion shaft, preventing oil leaks and ingress of dirt or debris. With a bore diameter of 2.374 inches and an outside diameter of 2.378 inches, this seal fits precisely in compatible differential housings. The 1.375-inch width offers a robust sealing surface to maintain integrity under operational stresses.

Applications and Problem Solving

This differential pinion seal is suitable for use in a range of vehicles requiring a reliable seal for the pinion shaft in the differential assembly. It addresses common issues such as:

  • Preventing differential oil leaks that can lead to lubrication failure
  • Reducing contamination from dirt and moisture entering the differential
  • Maintaining proper differential function by preserving internal fluid levels
  • Minimizing wear on the pinion shaft and bearings due to effective sealing

Installation Notes and Tips

When installing the FAG SS2420 differential pinion seal, ensure the sealing surface and bore are clean and free of debris. Use appropriate tools to press the seal evenly into place without damaging the sealing lip or metal casing. Verify the seal orientation matches the auxiliary lip direction to optimize sealing performance. Proper installation helps avoid premature seal failure and maintains differential integrity.

Quality Assurance and Warranty

FAG manufactures the SS2420 differential pinion seal to meet stringent quality standards for automotive sealing components. The use of nitrile material and metal spring design ensures durability and consistent performance. While specific warranty details are not provided, FAG products typically adhere to industry standards for reliability and longevity in driveline applications.
