385AS-384ED TDO (Two-Row Double-Outer Race) (Imperial)

385AS-384ED TDO (Two-Row Double-Outer Race) (Imperial)

The 385AS-384ED is a two-row tapered roller bearing with a 2″ bore and 3.937″ outer diameter, built from sturdy chrome steel for combined load handling. It supports dynamic radial loads up to 35,600 lbf and fits imperial-sized machinery.

Its double-row design boosts load capacity, while the open seal allows easy lubrication. The steel cage ensures smooth operation, even at temperatures from -30°C to 110°C.

This bearing is ideal for heavy-duty applications like truck axles or industrial gearboxes where both radial and thrust loads are present. It comes with standard radial clearance but can be ordered in C3/C4/C5 options.

Weighing 3.52 lb, it’s robust yet manageable for installation. Compliant with RoHS and REACH standards, it’s a reliable choice for replacements or new builds.
