Timken HM262749D Tapered Double Inner Roller Bearing

The Timken HM262749D is a TDI (Tapered Double Inner) double-cone tapered roller bearing assembly designed to support extremely high combined radial and axial loads in heavy-duty rotating equipment. It is 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, and maintenance teams, OEMs, and system integrators use this double cone bearing for equipment repair, replacement, major rebuilds, and heavy-duty drivetrain retrofits. This bearing features a 13.6250 in (346.075 mm) bore, a 19.2500 in (488.950 mm) outside diameter, and a 6.8750 in (174.625 mm) bearing width (T) with a 6.8750 in (174.625 mm) double cone width (B); it uses a pin-type cage and is made from high-grade bearing steel. The dynamic radial load rating (C1) is 676,000 lbf (3,010,000 N) and the C90 rating is 101,000 lbf (448,000 N), reflecting its suitability for demanding applications. It is designed with a non-standard shoulder and is typically supplied as part of a preset TDI assembly, compatible with Timken HM262710 cups. Common replacements include the Timken HM262710 cup and HM262749D/HM262710 bearing assemblies, or HM262749DG/HM262710 assemblies.
