Precision Parts A17 Tapered Roller Bearing Set Cone L68149 Cup L68111

The Precision Parts A17 is a complete tapered roller bearing set consisting of a matched cone (L68149) and cup (L68111) assembly. Engineered for demanding automotive and powertrain applications, this bearing set delivers reliable performance under combined radial and axial load conditions.

The two-piece design features a detachable cone and cup: the cone (inner race) carries the tapered rollers and fits onto the rotating shaft, while the cup (outer race) seats in the housing and provides the rolling surface. The tapered roller geometry allows the bearing to efficiently manage both radial and axial loads simultaneously.
