TAPERED ROLLER BEARING SINGLE CUP

The Tapered Roller Bearing Single Cup is the precision outer raceway designed to pair with a matching single cone assembly. Its tapered outer ring raceway aligns with the cone’s geometry so roller lines converge at a common point on the bearing axis, delivering optimal load sharing and smooth rolling under combined radial and axial loads.

Manufactured to tight tolerances, the cup’s ground raceway supports accurate preload and end-float settings, stable running, and long service life. The separable design simplifies assembly, inspection, and replacement—install the cup in the housing, then fit the cone assembly to the shaft for quick, reliable setup.

Benefits

• Precision-ground tapered raceway for consistent load distribution

• Separable design for easy installation and servicing

• Supports accurate preload/end-float adjustment with the matching cone

• Durable construction for long, reliable service
