Timken HM262749D Tapered Double Inner Roller Bearing

Description:

The Timken HM262749D tapered roller bearing is a double cone (TDI – Tapered Double Inner) bearing assembly designed to support extremely high combined radial and axial loads in heavy-duty industrial rotating equipment. Commonly installed in rolling mills, industrial gearboxes, mining equipment, marine propulsion systems, and large power transmission assemblies where exceptional rigidity and load capacity are required. Maintenance teams, OEMs, and system integrators use this double cone bearing for equipment repair, replacement, major rebuilds, and heavy-duty drivetrain retrofits.

Applications:

The Timken HM262749D double cone bearing is engineered for demanding industrial applications requiring high load capacity, accurate shaft positioning, and long service life. It is widely used in rolling mills, mining and aggregate equipment, heavy-duty conveyors, marine drive systems, industrial gear reducers, and other large rotating machinery when paired with the compatible Timken HM262710 bearing cups in a TDI bearing arrangement.
