A single flanged cup is the outer ring (cup) of a tapered roller bearing designed with an axial flange. It works with a tapered cone to complete the bearing, and the flange enables fixed axial positioning in housings.

1. Secures the bearing axially, preventing movement along the shaft. 2. Simplifies housing design by eliminating the need for machined shoulders 3. Aligns and supports seals in through-bore installations

Flanged cups enable tapered roller bearings to handle radial loads and axial (thrust) loads in one direction. Clamp load-bearing comes from the cup insertion and cone placement.

1. Axial location: Built-in flange ensures precise axial positioning under load. 2. Simplified housing: eliminates the need for shoulders or stopping features 3. Service-friendly: separable design makes maintenance and replacement easier 4. High load capacity & durability: retains structural strengths of tapered geometry

1. Single-direction thrust: requires paired bearings for bidirectional axial loads. 2. Precise preload critical: incorrect clearance can severely limit life or cause failure. 3. Misalignment sensitivity: requires accurate installation and a firm housing fit
