This bearing cup forms the outer ring component of a two-piece tapered roller bearing system. The tapered design allows the bearing to support both radial and axial loads simultaneously, making it ideal for wheel hub applications that experience forces in multiple directions. The cup and cone assembly are separable and interchangeable, simplifying maintenance and replacement procedures.

Note: This is the bearing cup only. The matching cone bearing (LM25580) is sold separately and required for a complete bearing assembly.
