WJB WT3994 Rear Wheel Tapered Roller Bearing Cone

The WJB WT3994 is a precision-engineered tapered roller bearing cone designed for rear wheel applications in automotive vehicles. This bearing cone features a tapered design that allows it to handle both radial and thrust loads simultaneously, making it ideal for wheel hub assemblies where forces come from multiple directions.

Key Features:

• Premium tapered roller bearing cone construction for superior load distribution
• Precision-ground raceways ensure smooth operation and extended service life
• High-quality steel construction with heat treatment for maximum durability
• Direct cross-reference replacement for National 3994, Timken 3994, and SKF BR3994
• Designed specifically for rear wheel bearing applications
• Meets or exceeds OEM specifications for fit and performance

Application Notes:

This bearing cone is part of a tapered roller bearing set and must be used with the appropriate bearing cup (race) for proper installation. Tapered roller bearings require proper adjustment during installation to ensure correct preload and optimal performance. Always inspect the bearing cup for wear or damage when replacing the cone, and replace both components together when necessary.
