Inch Series Tapered Roller Bearings | Precision Cone & Cup Design for Industrial Applications
Tapered roller bearings also come in Inch Series specifications. The designations of inner ring assemblies and outer rings of inch-design bearings (excluding four-row tapered roller bearings) are formulated differently:
In tapered roller bearings, the outer ring is sometimes referred to as the “cup” and the inner ring assembly as the ”cone". These are sometimes called “sub-units”, with a single bearing referred to as a “unit”.
Bearing designations are formed with the code for the inner ring assembly first, followed by the code for the outer ring.
