Single Cups (Imperial)

What Are Single Cups (Imperial)?

Single Cups (Imperial) refer to the outer ring (cup) of tapered roller bearings manufactured to inch (imperial) dimensions. These cups consist of a hardened and precision‑ground raceway designed to support tapered rollers and transmit radial and axial loads when paired with an inner ring (cone).

Structure and Function

The cup serves as the stationary component of the bearing assembly, providing a robust raceway surface for the rollers to roll against. Combined with the matching cone, it creates a complete bearing capable of handling combined loads in industrial and automotive applications.

Key Features

• Hardened, precision‑ground raceway for smooth operation
• Manufactured to imperial standards for compatibility with inch‑based systems
• High load‑carrying capacity for heavy‑duty use
• Interchangeable design for easy replacement and maintenance

Typical Applications

• Automotive wheel hubs and differentials
• Heavy trucks and trailers
• Agricultural machinery
• Industrial gearboxes and drivetrains

Interchangeability

These cups are dimensionally and functionally interchangeable with equivalent components from top brands such as SKF and Timken, ensuring flexibility in both OEM and aftermarket scenarios.

Why Choose Imperial Single Cups?

By selecting Single Cups (Imperial), engineers and maintenance teams benefit from standardized dimensions, global availability, and proven durability. Their precision raceway ensures optimal performance, while interchangeability reduces procurement complexity.

Conclusion

For any inch‑based tapered roller bearing assembly, Single Cups (Imperial) provide the critical outer‑ring component needed for long‑lasting, high‑performance operation. Pair them with matching cones to complete your bearing solutions.
