463-452D TDO (Two-Row Double-Outer Race) (Imperial)

463-452D TDO (Two-Row Double-Outer Race) (Imperial)

The 463-452D is a two-row tapered roller bearing with a 1.875″ bore and 4.25″ outer diameter, built from sturdy chrome steel. It handles combined loads well, with a dynamic radial capacity of 53,100 lbf and smooth operation up to 110°C.

Its double-row design spreads loads evenly, while the open construction allows easy lubrication. The steel cage keeps rollers aligned for consistent performance over time.

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

Weighing 6.13 lb, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards, it’s a reliable choice for replacements or new builds. ABEC-1 rated for general precision needs.
