Timken M12411DB Double Cone Tapered Roller Bearing Assembly

Description:

The Timken M12411DB is a matched double-cone tapered roller bearing assembly consisting of two precision M12448 cones (inner ring assemblies) supplied as a factory-matched pair with a bearing spacer. This assembly is designed to operate with the appropriate matching double cup to support heavy combined radial and axial loads while maintaining controlled preload and end play in demanding applications. Commonly installed in industrial gearboxes, conveyors, mining equipment, construction machinery, agricultural equipment, and power transmission systems, the matched double-cone assembly provides accurate shaft positioning, high load capacity, and reliable long-term performance. Maintenance teams, OEMs, and system integrators specify the Timken M12411DB assembly for equipment repair, replacement, machine rebuilds, and retrofits where factory-matched bearing components are required for optimum performance.

Applications:

The Timken M12411DB matched double-cone assembly is intended for heavy-duty industrial applications requiring high rigidity and accurate axial location under combined radial and thrust loads. It is commonly used in industrial gear reducers, heavy-duty conveyors, mining and aggregate equipment, construction machinery, agricultural equipment, and power transmission systems where matched tapered roller bearing assemblies provide precise shaft alignment, controlled preload, efficient load distribution, and extended operating life.
