QA1 GEZ63ES Fractured Race Spherical Bearing 2.5" Bore

The QA1 GEZ63ES is a commercial-grade fractured race spherical bearing engineered for high-wear and increased-load applications in automotive, industrial, and motorsports environments. Manufactured from premium 52100 bearing steel, this bearing delivers exceptional durability and performance in demanding conditions.

Key Features:

• 2.5-inch bore diameter with 3.938-inch outer diameter
• 52100 bearing steel construction for both ball and race components
• Protective coating on ball and race for enhanced corrosion resistance
• Fractured race design allows for optimal ball insertion and secure assembly
• Hardened and ground surfaces ensure full ball-to-race conformity
• Metal-to-metal contact design for extreme load capacity
• Relubricatable with grease grooves and through-holes for extended service life
• Self-aligning capability accommodates angular misalignment up to 6 degrees
• Race width: 1.875 inches, Inner ball width: 2.187 inches

The fractured race design is a key feature of this bearing. Because of the exceptional strength of 52100 steel, the race cannot be molded around the ball and is therefore fractured slightly to allow ball insertion. This manufacturing method, combined with precision hardening and grinding, results in reduced wear, smoother operation, and minimized localized stress. Ideal for suspension linkages, control arms, steering components, and heavy-duty industrial equipment where reliability is critical.
