A single cup is the outer ring (raceway) of a single-row tapered roller bearing. Together with a cone (inner ring, rollers, and cage), it forms a complete bearing capable of supporting radial and axial loads.

While cups don't carry loads themselves, when assembled with cones, they enable bearings to handle radial loads and unidirectional axial loads. The geometry determines thrust capacity.

Match the cup's series and internal dimensions with a compatible cone. Ensure correct bore, width, and contact angle for your speed, load, and clearance requirements.

High alloy or chrome steel is standard, offering strength and heat resistance up to ~120 °C. Carburized steel options are available for specific applications.

Cups are typically press-fitted into housings, while cones slip onto the shaft. Assembly position determines internal clearance or preload for optimal bearing performance.

1. Standard cups —straight ring 2. Flanged cups —include flange for axial positioning in housings 3. Precision cups —tighter tolerances for smooth operation

Essential in assembling: 1. Automotive wheel hubs 2.Gearboxes and axles 3.Industrial machinery (conveyors, mining, and agricultural equipment)
