Precision Parts A15 Tapered Roller Bearing Cone and Cup Set L45449/L45410

The Precision Parts A15 is a tapered roller bearing cone and cup set, also known by the industry interchange number L45449/L45410. This complete two-piece bearing set consists of the cone (inner ring assembly with tapered rollers and cage) and the cup (outer ring), engineered to handle both radial and axial loads in demanding automotive and industrial applications.

The A15 bearing set measures 1-9/64" inner diameter x 1-63/64" outer diameter x 9/16" width and is constructed from Chrome Steel SAE-52100 for exceptional hardness, durability, and resistance to deformation under load. The tapered roller design allows for efficient load distribution across the raceway surfaces, minimizing friction and extending service life.
