The 25580/25520 Tapered Roller Bearing is a single-row, inch-series tapered roller bearing consisting of a cone assembly (inner ring, tapered rollers, and cage) and a cup (outer ring). Its tapered raceway design enables it to support combined radial and axial loads, making it suitable for applications requiring reliable load handling, stable rotation, and long service life. The separable design simplifies mounting, inspection, and maintenance.
