The Timken Company L630349 Tapered Roller Bearing

Description:

The Timken L630349 tapered roller bearing cone is a precision single cone (inner ring assembly) with a 6.000-inch bore and a 0.9449-inch inner ring width, engineered to support heavy combined radial and axial loads when paired with the matching Timken L630310 cup (outer ring) to form a complete tapered roller bearing set. Commonly installed in industrial gearboxes, conveyors, mining equipment, construction machinery, agricultural equipment, and power transmission systems, this bearing cone provides precise shaft alignment, excellent load-carrying capacity, and dependable long-term performance in demanding industrial environments. Maintenance teams, OEMs, and system integrators specify the Timken L630349 tapered roller bearing cone for equipment repair, replacement, machine rebuilds, and retrofits where reliable bearing performance and extended service life are essential.

Applications:

The Timken L630349 tapered roller bearing cone is designed for heavy-duty industrial applications requiring reliable performance under combined radial and axial loads. It is widely used in industrial gear reducers, heavy-duty conveyors, mining and aggregate equipment, construction machinery, agricultural equipment, and power transmission systems where it operates with the Timken L630310 cup to provide accurate shaft positioning, efficient load distribution, reduced friction, and extended bearing service life.
