Detailed Description

SKF 12751 is a rear differential pinion seal engineered for the Mazda Miata platform from 1990 through 1994. The seal dimensions are specified for the pinion shaft area, with a 1.260-inch shaft diameter, 2.137-inch outside diameter, and 0.394-inch width. The polyacrylate sealing surface is selected to match the operating environment of the application and support consistent sealing performance. If you are searching for a rear differential pinion seal for a 1990-1994 Mazda Miata, SKF 12751 is the direct fitment reference. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

  • Rear differential gear oil seepage at the pinion area
  • Contamination entering the differential housing through a worn seal
  • Lubricant loss that can affect driveline operation
  • Seal wear from age, heat, and mileage on Mazda Miata rear axles

Installation Notes and Tips

Confirm the shaft diameter, outside diameter, and width before installation to match the original seal dimensions. Inspect the pinion yoke and sealing surface for wear, scoring, or corrosion before fitting the new seal. Clean the housing bore and surrounding area thoroughly so the seal seats evenly. For best results, verify rear axle fitment on 1990-1994 Mazda Miata models before ordering SKF 12751.

Quality Assurance

SKF has a long history in seal engineering, including early integrated shaft seal development and continued refinement of sealing materials and bonding methods. SKF 12751 is manufactured to defined specifications using premium materials for the stated application.
