BBB Precision 11563 Tapered Roller Bearing Cup

The BBB Precision 11563 is a tapered roller bearing cup (outer race) designed for use in demanding industrial, automotive, and heavy-duty applications. Engineered to exacting tolerances, this cup pairs with compatible tapered roller bearing cones to handle combined radial and thrust loads with high efficiency and long service life.

Key Features:

• Precision-ground raceway for smooth, consistent roller contact and reduced operating noise
• High-quality bearing steel construction for superior hardness, wear resistance, and fatigue life
• Tight dimensional tolerances conforming to ABMA/ANSI standards for interchangeability with equivalent cups in the 11563 bearing series
• Corrosion-resistant finish to protect against rust during storage and normal operating conditions
• Direct OEM-equivalent replacement compatible with other major bearing brands in the same series

The 11563 cup is part of the widely used imperial tapered roller bearing series and is interchangeable with equivalent parts from other manufacturers. It is commonly found in axle, wheel hub, transmission, differential, and machine tool applications requiring precise load distribution and reliable performance.
