Timken LM742749-LM74210CD Tapered Roller Bearing Assembly

Description:

The Timken LM742749–LM74210CD is a precision tapered roller bearing assembly consisting of a single cone (inner ring assembly) and a double cup (outer ring assembly), designed in the TDO (Tapered Double Outer) configuration to support heavy combined radial and axial loads while providing excellent rigidity and accurate shaft positioning. This bearing assembly is commonly installed in industrial gearboxes, conveyors, mining equipment, construction machinery, agricultural equipment, and power transmission systems where high load capacity and dependable operation are required. Maintenance teams, OEMs, and system integrators specify the Timken LM742749–LM74210CD tapered roller bearing assembly for equipment repair, replacement, machine rebuilds, and retrofits requiring genuine Timken matched bearing components.

Applications:

The Timken LM742749–LM74210CD tapered roller bearing assembly is engineered for demanding industrial applications requiring reliable support for combined radial and axial loads with increased stiffness. It is widely used in industrial gear reducers, heavy-duty conveyors, mining and aggregate equipment, construction machinery, agricultural equipment, and power transmission systems where the TDO bearing configuration provides precise shaft alignment, efficient load distribution, and extended bearing service life under continuous heavy-duty operating conditions.
