Elring Differential Seal 505.090 Overview

The Elring 505.090 differential seal is engineered to provide reliable sealing performance for driveline and axle applications. Made from durable ACM (polyacrylate) material, this differential seal is designed to maintain optimal sealing under demanding conditions, helping to protect your vehicle's differential components.

• Material: ACM (polyacrylate) for enhanced chemical and temperature resistance
• Inside Diameter: 29.9 mm
• Outside Diameter: 47.0 mm
• Height: 11.3 mm
• Includes dust cover with dust lip for added protection
• Radial shaft seal design: ASW
• Swirl type: RD for improved sealing efficiency

Technical Details and Design Features

The Elring 505.090 differential seal features a precise radial shaft seal design (ASW) that ensures a tight fit around the shaft, minimizing the risk of leaks. The ACM (polyacrylate) material offers excellent resistance to oils, greases, and heat, making it suitable for use in various automotive differentials. The integrated dust cover with a dust lip helps prevent contamination from dirt and debris, extending the service life of the seal and the differential components it protects. With an inside diameter of 29.9 mm and an outside diameter of 47.0 mm, this seal fits specific differential housings requiring these dimensions. The 11.3 mm height and swirl type RD design contribute to maintaining a secure and effective seal under rotational stress.

Applications and Common Issues Addressed

• Prevents oil leaks from the differential housing
• Protects differential bearings from dirt and dust ingress
• Reduces wear caused by contamination and fluid loss
• Maintains proper lubrication within the differential assembly
• Helps avoid costly repairs due to seal failure in driveline systems

Installation Notes and Tips

When installing the Elring 505.090 differential seal, ensure the sealing surfaces are clean and free of debris. Use appropriate tools to press the seal evenly into the housing without damaging the dust lip. Verify the seal orientation, with the dust lip facing outward to provide maximum protection against contaminants. Lubricate the seal lip lightly with compatible differential oil before installation to reduce initial wear. Check the fitment dimensions carefully to confirm compatibility with your vehicle's differential assembly.
