One New Aftermarket Replacement Cone, Tapered Roller Bearing - 2878 Series (A-2878-P-AI)
This tapered roller bearing cone (inner ring assembly) serves as a direct aftermarket replacement for the Timken 2878 series single-row tapered roller bearing cone. The cone consists of the inner ring and tapered rollers, designed to work in conjunction with a matching cup (outer ring) to handle both radial and axial loads efficiently. It is widely used in agricultural equipment, construction machinery, industrial gearboxes, and drivetrain applications where combined load capacity and precision fit are required.
