455W-452D TDO (Two-Row Double-Outer Race) (Imperial)

455W-452D TDO (Two-Row Double-Outer Race) (Imperial)

The 455W-452D is a two-row tapered roller bearing with a 2″ bore and 4.25″ outer diameter, built from sturdy chrome steel for long-lasting performance. It handles combined loads with a dynamic radial capacity of 53,100 lbf and operates smoothly in temperatures from -30°C to 110°C.

Its open design allows for easy lubrication, while the steel cage ensures durability under heavy use. The double-row construction provides stability, making it suitable for high-load applications.

This bearing is ideal for industrial machinery, gearboxes, or heavy equipment where both radial and thrust loads are present. It comes in standard radial clearance but can also be ordered in C3, C4, or C5 options for specific needs.

Weighing 5.83 lb, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards, it’s a reliable choice for replacements or new installations.
