Tapered roller bearing outer rings for radial assemblies
The outer ring of a tapered roller bearing, commonly called the cup, is a precision-ground component that houses the roller set and defines the bearing's load capacity and contact geometry. When a bearing assembly shows wear or damage, replacing only the cup rather than the entire bearing is often the most practical and cost-effective repair, provided the cone and rollers remain within specification.
This range includes over 60 individual outer rings covering a wide spread of bore diameters and widths suited to single-row tapered roller bearing assemblies used in gearboxes, wheel hubs, differential housings and industrial spindle arrangements. Taper angles across the range vary to match different load combinations, from shallow angles for predominantly radial loads to steeper angles that handle greater axial thrust.
Each cup is manufactured to the dimensional and surface finish tolerances required for interference or transition fits in standard housings, ensuring proper preload and alignment when paired with the matching cone assembly. For maintenance engineers, drivetrain specialists and bearing distributors who need specific outer ring replacements, having access to individual cups avoids the expense of purchasing complete bearing sets when only one component has reached the end of its service life.
