Precision Parts A1 Tapered Roller Bearing Cone and Cup Set

The Precision Parts A1 is a tapered roller bearing cone and cup set, commonly used in trailer hubs, agricultural equipment, utility axles, and light industrial applications. The matched cone and cup assembly is designed to handle both radial and axial (thrust) loads simultaneously, making it ideal for wheel-end and rotating shaft applications.

Key Features:

• Tapered roller design for efficient handling of combined radial and thrust loads
• Precision-ground races on both cone and cup for smooth, consistent operation
• Hardened steel construction for long service life and durability
• Industry-standard A1 dimensions for broad cross-reference compatibility
• Matched cone and cup set included for complete bearing replacement

The A1 bearing is a widely cross-referenced part number compatible with many OEM applications. It is a go-to replacement bearing for trailer axles, boat trailers, utility trailers, and similar light-duty wheel-end uses. Always replace cone and cup together for optimal performance and longevity.
