Timken 52400/52637D Double Tapered Roller Bearing

Description:

The Timken 52400/52637D Double Tapered Roller Bearing is a TDO (Tapered Double Outer) bearing assembly consisting of the 52400 cone and 52637D double cup, engineered to support heavy combined radial and axial loads while providing exceptional rigidity and resistance to overturning moments. Its double-row configuration makes it ideal for demanding industrial equipment such as rolling mills, industrial gearboxes, mining machinery, construction equipment, and heavy-duty power transmission systems.

Applications:

The Timken 52400/52637D TDO Bearing is designed for heavy-duty applications requiring high load capacity, precise shaft positioning, and long operating life. The TDO configuration provides a wide effective bearing spread, allowing it to handle combined radial and thrust loads in fixed or floating mounting arrangements. It is commonly used in rolling mills, industrial gearboxes, mining and aggregate equipment, paper processing machinery, heavy conveyors, and other demanding power transmission equipment.
