Timken L217849/L217810DC/L217848C Double Tapered Roller Bearing

Description:

The Timken L217849/L217810DC/L217848C double tapered roller bearing is a precision TDO (Tapered Double Outer) bearing assembly consisting of two L217849 cones (inner ring assemblies), one L217810DC double cup (outer ring), and the L217848C spacer. This matched bearing set is engineered to support heavy combined radial and axial loads while maintaining precise shaft positioning and controlled internal clearance in demanding industrial applications. Commonly installed in industrial gearboxes, conveyors, mining equipment, construction machinery, agricultural equipment, and power transmission systems, this double-row tapered roller bearing assembly is specified by maintenance teams, OEMs, and system integrators for equipment repair, replacement, machine rebuilds, and retrofits where high rigidity, extended service life, and reliable performance are required.

Applications:

The Timken L217849/L217810DC/L217848C double tapered roller bearing assembly is designed for heavy-duty industrial machinery operating under high radial and thrust loads. It is widely used in industrial gear reducers, rolling mills, heavy-duty conveyors, mining and aggregate equipment, construction machinery, agricultural equipment, and other power transmission systems where the matched double-row bearing assembly delivers accurate shaft alignment, improved load distribution, and long operating life under continuous service conditions.
