Technical Details and Material Specifications

The SKF differential pinion seal part number 15382 features a polyacrylate sealing surface, which offers improved durability and chemical resistance compared to traditional rubber seals. The seal’s dimensions—2.960 inches outside diameter, 1.535 inches shaft diameter, and 0.647 inches width—are designed to match the differential pinion shaft and housing precisely, minimizing the risk of oil leaks and contamination ingress. This precision fit is critical for maintaining the integrity of the driveline and axle assembly in Mazda 929 and RX-7 vehicles.

Applications and Problem Solving

• Prevents differential oil leaks that can cause driveline damage
• Protects against dirt and debris entering the differential housing
• Reduces wear on the pinion shaft by maintaining proper lubrication
• Helps maintain consistent differential performance and longevity
• Addresses common seal failure issues in Mazda 929 and RX-7 differentials

Installation Notes and Tips

When installing the SKF 15382 differential pinion seal, ensure the shaft and housing surfaces are clean and free of debris. Use appropriate tools to press the seal evenly into the housing without distortion. Lubricate the sealing surface lightly with differential oil before installation to prevent dry running during initial operation. Verify the seal is seated flush and aligned correctly to avoid premature wear or leaks.

Quality Assurance and Warranty

SKF manufactures the 15382 differential pinion seal to meet strict quality standards, ensuring reliable performance in Mazda 929 and RX-7 driveline systems. The polyacrylate sealing surface is tested for resistance to heat, oil, and mechanical wear.
